feat: Add option to restrict credential usage in http request node

[Joffcom]

Expect this to change as we test different ideas / approaches

Summary

This is the start of a PR to implement a feature where we can set an allowlist or similar on some credential types to restrict what sites the http request node can use them with.

At the moment an option is added to OAuth credentials, generic credentials and any pre-defined credential that contains the Authenticate method.]
