cloudcode.yaml.crdSchemaLocations wildcard (*/**) path support

[codysmithd]

Use case
Working on a large project, with lots of CRDs in lots of YAML definition files in a deeply-nested build output directory.

Feature
The existing crdSchemaLocations would have support for globs, and visual-studio-code settings built-ins like ${workspaceFolder}.

e.g.

"cloudcode.yaml.crdSchemaLocations": [
    "${workspaceFolder}/bazel-output/crds/**/*.yaml"
 ]

Which would match files:

• bazel-output/crds/myThing/definition.yaml
• bazel-output/crds/otherThing/nestedDeeper/definition.yaml
  etc.

Ideally, this would also be tolerant of YAML files that match the glob and are not CRDs too (and would just ignore them).
