When parsing resource IDs (probably incorrectly since they are URIs and
should therefore be opaque), we need to look for "resourcegroups" in
addition to "resourceGroups" because the Azure CDN resources return that
in their URIs.
Unfortunately the casing semantics of the rest of the string are not
clear, so downcasing the entire URI is probably best avoided. This is a
fix for a single case.
Fixes#4721. It seems there may be some eventual consistency in the API
for network ACLs. This fix doesn't use resource.WaitForState() as there
the NACL is not something that can be looked up by ID and has a
property which determines if it is present.
Instead we reuse the findNetworkAclRule function which the Read function
exhibiting the problem uses, and retry over a 3 minute period, returning
an error message informing the user that running `terraform apply` again
will likely allow them to continue.
In most cases private keys are used to produce certs and cert requests,
but there are some less-common cases where the PEM-formatted keypair is
used alone. The public_key_pem attribute supports such cases.
This also includes a public_key_openssh attribute, which allows this
resource to be used to generate temporary OpenSSH credentials, so that
e.g. a Terraform configuration could generate its own keypair to use
with the aws_key_pair resource. This has the same caveats as all cases
where we generate private keys in Terraform, but could be useful for
temporary/throwaway environments where the state either doesn't live for
long or is stored securely.
This builds on work started by Simarpreet Singh in #4441 .
The implementation was attempting to capture the error using a scoped
variable reference, but the error value is already exposed via the
return value of `WaitForState()`. Using that instead fixes the data
race.

As the command completes, the winrm.Command does not wait for its copy of
the remote.Command streams to report itself completed.
This adds an additional sync.WaitGroup to ensure that copy is finished up
before moving on, solving the data race.

==================
```
The render code path in `template_file` was doing unsynchronized access
to a shared mapping of functions in `config.Func`.
This caused a race condition that was most often triggered when a
`template_file` had a `count` of more than one, and expressed itself as
a panic in the plugin followed by a cascade of "unexpected EOF" errors
through the plugin system.
Here, we simply turn the FuncMap from shared state into a generated
value, which avoids the race. We do more re-initialization of the data
structure, but the performance implications are minimal, and we can
always revisit with a perf pass later now that the race is fixed.
