[Response Ops] [Connectors] Move connectors to own plugin

[ymao1]

Towards #90931

Summary

Created stack_connectors plugin and moved the connectors from actions/server/built_in_action_types into this new plugin. This only addresses the server side code. All client side code is still in triggers_actions_ui/public/built_in_action_types and can be moved in a followup PR.

Notable changes:

• Moved non connector type specific functions from actions/server/built_in_action_types/lib into the top level lib folder in actions/server/lib. Connector type specific functions were moved with the connector type.
• Many connector type definitions were still currying actionConfigurationUtilities in the executor function, so I refactored so those utilities are passed into the executor by the action_executor.
• Moved an email specific (internal) route out of the actions plugin.
• Tried to use the updated terminology inside the new plugin.
• Split connector types into stack and cases
  • stack types are .email, .index, .pagerduty, .server-log, .slack, .teams, .webhook
  • cases types are .cases-webhook, .jira, .resilient, .servicenow, .servicenow-sir, .servicenow-itom, .swimlane, .xmatters

Followup PRs for moving the client side code and splitting out functional tests

To Verify

Ensure you can create and execute all connector types.

These were unused so I deleted them.

Looks good! I tested the Swimlane and Jira connectors. I reached out to @EricDavisX and sounds like the QA team should be able to test out the remaining connectors 👍
