config: smarter provider alias usage validation
Fixes #4789

This improves the validation that valid provider aliases are used.

Previously, we required that provider aliases be defined in every module
they're used. This isn't correct because the alias may be used in a
parent module and inherited.

This removes that validation and creates the validation that a provider
alias must be defined in the used module or _any parent_. This allows
inheritance to work properly.

We've always had this type of validation for aliases because we believe
its a good UX tradeoff: typo-ing an alias is really painful, so we
require declaration of alias usage. It may add a small burden to
declare, but since relatively few aliases are used, it improves the
scenario where a user fat-fingers an alias name.

config: Merge respects Terraform blocks, provider aliases, and more
Fixes #10715

`config.Merge` was not updated to support a number of new features. This
updates the codepath to merge various fields, including the `terraform`
block which was the issue in #10715.

The `Merge` API is called when an `_override` file is present to _merge_
configurations. Normally configurations are _appended_. Only an override
file triggers a _merge_.

I started working on a generic library to do this automatically awhile
back but never finished it. This might motivate me to do so. In the
interest of getting a fix out though, we'll continue the manual
approach.

config: error when loading multiple lifecycle blocks

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.

Martin Atkins 399542a168 core: allow outputs to have descriptions (#9722)
We allow variables to have descriptions specified, as additional context
for a module user as to what should be provided for a given variable.

We previously lacked a similar mechanism for outputs. Since they too are
part of a module's public interface, it makes sense to be able to add
descriptions for these for symmetry's sake.

This change makes a "description" attribute valid within an "output"
configuration block and stores it within the configuration data structure,
but doesn't yet do anything further with it. For now this is useful only
for third-party tools that might parse a module's config to generate
user documentation; later we could expose the descriptions as part of
the "apply" output, but that is left for a separate change.

config: maintain slice index accounting for computed keys
Fixes #10075
Fixes #10013

When interpolating, we were only maintaining the last known slice index.
If you had sibling slices then you could lose your slice index when
exiting the slice. The resulting behavior was that no some runs the
computed key would be: "slice.0.attr" and on others would be
"slice.attr", the latter being incorrect.

We now maintain a list of slice indexes so that as we unnest, we
properly restore the old value.

Surprisingly unrelated to the graph but the shadow graph caught this
which is great. :)

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: formatlist accepts an empty list
Fixes #7607

An empty list is a valid value for formatlist which means to just return
an empty list as a result. The logic was somewhat convoluted here so I
cleaned that up a bit too. The function overall can definitely be
cleaned up a lot more but I left it mostly as-is to fix the bug.

James Nugent 47bce79b29 core: Add zipmap interpolation function
This commit adds a new interpolation function, zipmap, which produces a
map given a list of string keys and a list of values of the same length
as the list of keys.

The name comes from the same operation in Clojure (and likely other
functional langauges).

config: ignore_changes cannot have interpolations
This is the limitation of all lifecycle attributes currently. Right now,
interpolations are allowed through and the user ends up thinking it
should work. We should give an error.

In the future it should be possible to support some minimal set of
interpolations (static variables, data sources even perhaps) but for now
let's validate that this doesn't work.

config/module: use the raw source as part of the key
This changes the key for the storage to be the _raw_ source from the
module, not the fully expanded source. Example: it'll be a relative path
instead of an absolute path.

This allows the ".terraform/modules" directory to be portable when
moving to other machines. This was a behavior that existed in <= 0.7.2
and was broken with #8398. This amends that and adds a test to verify.

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.
