* chore(docs): update docs re workspace tag default values
* chore(coderdenttest): use random name instead of t.Name() in newExternalProvisionerDaemon
* fix(provisioner/terraform/tfparse): allow empty values in coder_workspace_tag defaults
Relates to https://github.com/coder/coder/issues/15977
Adds support for some functions in `tfparse` (only functions that do not
reference local files).
NOTE: for now, I'm importing trivy-iac. If we prefer to avoid a little
dependency, I can do a little copying instead.
* Improves tfparse test coverage to include more parameter types and values
* Adds tests with unrelated parameters that should be ignored by tfparse
* Modifies tfparse to only attempt evaluation of parameters referenced by coder_workspace_tags
Refactors our use of `slogtest` to instantiate a "standard logger" across most of our tests. This standard logger incorporates https://github.com/coder/slog/pull/217 to also ignore database query canceled errors by default, which are a source of low-severity flakes.
Any test that has set non-default `slogtest.Options` is left alone. In particular, `coderdtest` defaults to ignoring all errors. We might consider revisiting that decision now that we have better tools to target the really common flaky Error logs on shutdown.
