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: validate invalid variable keys
Fixes #9416

A simple change to verify that only valid keys for `variable` blocks are
used.

config: error when loading multiple lifecycle blocks
Fixes #8776

This introduces an error when multiple `lifecycle` blocks exist on a
resource in the configuration.

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.

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.

James Bardin a3fc7e2e21 remove "count" while loading a data source
Data sources should be able to support counts like a resource. We need
to remove "count" when we load the config because the key doesn't exist
in the schema, and the resource won't validate.

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.

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.

Matt Good 21b0a03d70 Support for multiple providers of the same type
Adds an "alias" field to the provider which allows creating multiple instances
of a provider under different names. This provides support for configurations
such as multiple AWS providers for different regions. In each resource, the
provider can be set with the "provider" field.

(thanks to Cisco Cloud for their support)
