Add support for filtering, paginating, and omitting allowedValues in metadata responses in Jira Cloud REST API

• Scope: Metadata endpoints such as:
  createmeta
  getIssueTypeMetaWithFields (and related issue‑creation metadata APIs)

• Requested capabilities:

Filtering allowedValues

• Example: support filters like released=false for fixVersions / affectedVersions or similar status-based filters.

Pagination / limiting

• Ability to page or cap the number of allowedValues returned (e.g. via startAt / maxResults-style params or equivalent).

Schema-only mode

• A way to omit allowedValues entirely while still returning full field schema (e.g. through expand options or a specific query parameter).
