James Nugent 681d94ae20 core: Allow lists and maps as variable overrides 
Terraform 0.7 introduces lists and maps as first-class values for
variables, in addition to string values which were previously available.
However, there was previously no way to override the default value of a
list or map, and the functionality for overriding specific map keys was
broken.

Using the environment variable method for setting variable values, there
was previously no way to give a variable a value of a list or map. These
now support HCL for individual values - specifying:

    TF_VAR_test='["Hello", "World"]'

will set the variable `test` to a two-element list containing "Hello"
and "World". Specifying

    TF_VAR_test_map='{"Hello = "World", "Foo" = "bar"}'

will set the variable `test_map` to a two-element map with keys "Hello"
and "Foo", and values "World" and "bar" respectively.

The same logic is applied to `-var` flags, and the file parsed by
`-var-files` ("autoVariables").

Note that care must be taken to not run into shell expansion for `-var-`
flags and environment variables.

We also merge map keys where appropriate. The override syntax has
changed (to be noted in CHANGELOG as a breaking change), so several
tests needed their syntax updating from the old `amis.us-east-1 =
"newValue"` style to `amis = "{ "us-east-1" = "newValue"}"` style as
defined in TF-002.

In order to continue supporting the `-var "foo=bar"` type of variable
flag (which is not valid HCL), a special case error is checked after HCL
parsing fails, and the old code path runs instead.
