fix: exclude api/v4/jobs/request for workhorse_api apdex in get-hybrid

What

This excludes an additional route (api/v4/jobs/request) from the workhorse_api apdex for the get-hybrid stack.

Why

This route is excluded in general from .com metrics. The get-hybrid stack includes it and we have found that when CiLongPolling is enabled, this causes the workhorse_api apdex to melt.

This is a minimal change to adjust only the affected apdex, rather than all workhorse metrics.

Special thanks to @nduff for the assist in figuring out that we were indeed excluding different routes between .com and Dedicated (get-hybrid).
