This changes the representation of maps in the interpolator from the
dotted flatmap form of a string variable named "var.variablename.key"
per map element to use native HIL maps instead.
This involves porting some of the interpolation functions in order to
keep the tests green, and adding support for map outputs.
There is one backwards incompatibility: as a result of an implementation
detail of maps, one could access an indexed map variable using the
syntax "${var.variablename.key}".
This is no longer possible - instead HIL native syntax -
"${var.variablename["key"]}" must be used. This was previously
documented, (though not heavily used) so it must be noted as a backward
compatibility issue for Terraform 0.7.
Just wanted to call out that the CLI prompts for values for unset variables instead of an error. Guessing that was an enhancement somewhere along the line and just didn't get updated in the docs.
these changes were added to reflect what was required to run the tutorial on my local machine. Below is my context for the above changes:
```shell

If the error message above mentions requiring or modifying configuration
options, these are set using the `-backend-config` flag. Example:
-backend-config="name=foo" to set the `name` configuration

```
This means that terraform commands like `plan`, `apply`, `show`, and
`graph` will expand all modules by default.
While modules-as-black-boxes is still very true in the conceptual design
of modules, feedback on this behavior has consistently suggested that
users would prefer to see more verbose output by default.
The `-module-depth` flag and env var are retained to allow output to be
optionally limited / summarized by these commands.
