Adds support for importing normal and organization apps with the
heroku_app resource.
The resource itself depends on an `organization` value in the
configuration to switch behavior for the different kinds of apps, so
`schema.ImportStatePassthrough` is not sufficient.
Adds computed `arn` to security group data source

* aws_route53_record: More consistent unquoting of TXT/SPF records.
Before, 'flatten' would remove the first two quotes. This results in
confusing behavior if the value contained two quoted strings.
Now, 'flatten' we only remove the surrounding qutoes, which is more
consistent with 'expand'.
Should improve hashicorp/terraform#8423, but more could still be done.
* aws/route53: Cover new bugfix with an acceptance test
This was actually redundant anyway since HIL itself applied a similar
rule where any partially-unknown list would be automatically flattened
to a single unknown value.
However, now we're changing HIL to explicitly permit partially-unknown
lists so that we can allow the index operator [...] to succeed when
applied to one of the elements that _is_ known.
This, in conjunction with hashicorp/hil#51 and hashicorp/hil#52,
fixes#3449.
We use a third-party library "colorable" to translate VT100 color
sequences into Windows console attribute-setting calls when Terraform is
running on Windows.
colorable is not concurrency-safe for multiple writes to the same console,
because it writes to the console one character at a time and so two
concurrent writers get their characters interleaved, creating unreadable
garble.
Here we wrap around it a synchronization mechanism to ensure that there
can be only one Write call outstanding across both stderr and stdout,
mimicking the usual behavior we expect (when stderr/stdout are a normal
file handle) of each Write being completed atomically.
