services: search by integration key

[mastercactapus]

What problem would you like to solve? Please describe:
When debugging integrations with other systems, it may become necessary to lookup which service an integration key belongs to.

Describe the solution you'd like:
Add the ability to search on the Services list page with an integration key (matching what is copied from the integration key list page for all types).

Describe alternatives you've considered:
Connecting directly to the database and searching by key ID.
