Query jira projects by key or name

What does this MR do?

This MR touches a couple things:

1. #231394 (closed): overrides the default max_page_size from 100 to whatever size is returned by Jira API call. Jira API endpoint for projects returns all projects in one call, so there is no need to add pagination and make multiple API calls when we get all in one request.
2. no issue: there was a bug with filtering of project by name or key that this MR fixes.
