Alisdair McDiarmid 4e7607deb5 repl: Display multi-line strings as heredocs
The console and output formatter previously displayed multi-line strings
with escaped newlines, e.g. `"hello\nworld\n"`. While this is a valid
way to write the HCL string, it is not as common or as readable as using
the heredoc syntax, e.g.

<<EOF
hello
world
EOF

This commit adds heredoc detection and display to this formatter,
including support for indented heredocs for nested multi-line strings.
This change affects the apply, console, and output sub-commands.

Alisdair McDiarmid 8b2b569d6e repl: Improved value renderer for console outputs
Use a slightly modified value renderer from terraform-provider-testing
to display values in the console REPL, as well as outputs from the apply
and outputs subcommands.

Derived from code in this repository, MIT licensed:

Note that this is technically a breaking change for the console
subcommand, which would previously error if the user attempted to render
an unknown value (such as an unset variable). This was marked as an
unintentional side effect, with the goal being the new behaviour of
rendering "(unknown)", which is why I changed the behaviour in this
commit.

Martin Atkins f085af4ba6 command: update "terraform console" for HCL2
This now uses the HCL2 parser and evaluator APIs and evaluates in terms
of a new-style *lang.Scope, rather than the old terraform.Interpolator
type that is no longer functional.

The Context.Eval method used here behaves differently than the
Context.Interpolater method used previously: it performs a graph walk
to populate transient values such as input variables, local values, and
output values, and produces its scope in terms of the result of that
graph walk. Because of this, it is a lot more robust than the prior method
when asked to resolve references other than those that are persisted
in the state.

Martin Atkins 5659128126 repl: fix formatting of list and map values
The indent function was stripping out newlines, causing multi-element
lists and maps to be rendered incorrectly.

We were also not quoting strings in these nested structures, leading to
weird behavior if any expression punctuation or newlines were present in
these strings.

This part of Terraform will get a more serious overhaul as part of
switching to the new parser/interpreter implementation but this is a
tactical fix to make the results of this command more usable in the
short term.
