Ondra Kupka edad3048e9 kubectl: Cache Verifier.HasSupport calls 
The underlying implementation decodes OpenAPI schema on every HasSupport
call. This causes these calls to be expensive and noticable when many
resources are being applied.

This patch wraps the verifier with a thread-safe cache so that when many
resources of the same kind are being checked, only the first call
includes schema decoding.

This solution is specifically limited to the kubectl codebase without
any changes required in client-go, for now, although that is where the
issue is actually originating.
