config: parse description field for outputs
We added the description field in 0.9 but we never parsed it because we
didn't have a use for it. As we prepare to use this field, let's start
parsing it out

Martin Atkins 81b0c4b28d config: generate errors for unnamed blocks of various sources
We've been incorrectly validating (or not validating at all) the
requirement that certain blocks be followed by a name string, to prohibit
e.g. this:

    variable {}

and:

    variable = ""

Before this change we were catching this for most constructs only if
there were no _valid_ blocks of the same name in the same file. For
modules in particular, we were not catching this at all.

Now we detect this for all kinds of block (resources had a pre-existing
check, so aren't touched here) and produce a different error message
depending on which of the above incorrect forms are used.

This fixes #13575.

Justin Campbell c1c3127d8e config: Generate error copy from valid types map
Renders as:

```
Variable 'invalid_type' type must be one of [string, map, list] - 'not_a_type' is not a valid type

James Bardin 8bcb9e19ca restructure JSON terraform config block AST
When configuration is read out of JSON, HCL assumes that empty levels of
objects can be flattened, but this removes too much to decode into a
config.Terraform struct.

Reconstruct the appropriate AST to decode the config struct.

config: disallow names starting with ints
Fixes #10597

This disallows any names for variables, modules, etc. starting with
ints. This causes parse errors with the new HIL parser and actually
causes long term ambiguities if we allow this.

I've also updated the upgrade guide to note this as a backwards
compatibility and how people can fix this going forward.

command/import: load configurations and allow empty config dirs
Fixes #7774

This modifies the `import` command to load configuration files from the
pwd. This also augments the configuration loading section for the CLI to
have a new option (default false, same as old behavior) to
allow directories with no Terraform configurations.
For import, we allow directories with no Terraform configurations so
this option is set to true.

config: manually parse variable blocks for better validation
Fixes #7846

This changes from using the HCL decoder to manually decoding the
`variable` blocks within the configuration. This gives us a lot more
power to catch validation errors. This PR retains the same tests and
fixes one additional issue (covered by a test) in the case where a
variable has no named assigned.

config: JSON resource keys with only one item load properly GH-5140
When a resource has only a single key set, the HCL parser treats that
key as part of the overall set of object keys. This isn't valid since
we expect resources to have exactly two keys. In this scenario, we have
to "unwrap" the keys back into a set of objects.

James Nugent 9d6c629689 config: Update test to reflect new behaviour
Escaped quotes are no longer supported as HIL syntax (as of the last
update to HIL), so this commit changes the Terraform config-layer test
to verify the non-presence of this behaviour for 0.7.

Martin Atkins 860140074f config: Data source loading
This allows the config loader to read "data" blocks from the config and
turn them into DataSource objects.

This just reads the data from the config file. It doesn't validate the
data nor do anything useful with it.

Martin Atkins fc4fa10981 config: "ResourceMode" concept for resources
Previously resources were assumed to always support the full set of
create, read, update and delete operations, and Terraform's resource
management lifecycle.

Data sources introduce a new kind of resource that only supports the
"read" operation. To support this, a new "Mode" field is added to
the Resource concept within the config layer, which can be set to
ManagedResourceMode (to indicate the only mode previously possible) or
DataResourceMode (to indicate that only "read" is supported).

To support both managed and data resources in the tests, the
stringification of resources in config_string.go is adjusted slightly
to use the Id() method rather than the unusual type[name] serialization
from before, causing a simple mechanical adjustment to the loader tests'
expected result strings.

James Nugent cb6cb8b96a core: Support explicit variable type declaration
This commit adds support for declaring variable types in Terraform
configuration. Historically, the type has been inferred from the default
value, defaulting to string if no default was supplied. This has caused
users to devise workarounds if they wanted to declare a map but provide
values from a .tfvars file (for example).

The new syntax adds the "type" key to variable blocks:

```
variable "i_am_a_string" {
    type = "string"
}

variable "i_am_a_map" {
    type = "map"
}
```

This commit does _not_ extend the type system to include bools, integers
or floats - the only two types available are maps and strings.

Validation is performed if a default value is provided in order to
ensure that the default value type matches the declared type.

In the case that a type is not declared, the old logic is used for
determining the type. This allows backwards compatiblity with previous
Terraform configuration.

Paul Hinze 15e7927009 config: test covering escaped quotes syntax error
This was never intended to be valid syntax, but it worked in the old HCL
parser, and we've found a decent number of examples of it in the wild.

Fixed in https://github.com/hashicorp/hcl/pull/62 and we'll keep this
test in Terraform to cover the behavior.

Sander van Harmelen c62370f9e9 Add a function to load JSON directly
Without this 12 line function it’s impossible to use any of the
Terraform code without the need for having the files on disk. As more
and more people are using (parts of) Terraform in other software, this
seems to be a very welcome addition. It has no negative impact on
Terraform itself whatsoever (the function is never called), but it
opens up a lot of other use cases.

Next to the single new function, I renamed the existing function (and
related tests) to better reflect what the function does. So now there
is a `LoadDir` function which calls `LoadFile` for each file, which
kind of made sense to me, especially when now adding a `LoadJSON`
function as well.

But of course if the rename is a problem, I can revert that part as
it’s not related to the added `LoadJSON` function.

Thanks!

Kushal Pisavadia b40b7ce01a Do not read temporary editor files, fixes #548
This fixes a bug where Terraform would error with the following:

```
Error loading config: Error reading
/Users/rhenrichs/work/example/.#example.tf: open
/Users/rhenrichs/work/example/.#example.tf: no such file or directory
```

The solution implemented here ignores the common emacs and vim
temporary file formats.

Note: the potential danger with merging this is that Terraform could
quickly have requests to ignore other file formats.
