Oncall Tools

[ioanarm]

The PR adds support for Grafana OnCall features to the MCP server, including:

• ListOnCallSchedules: Lists schedules from Grafana OnCall, with team ID filtering
• GetOnCallShift: Gets detailed information for a specific OnCall shift by ID
• GetCurrentOnCallUsers: Shows who's currently on-call for a specific schedule
• ListOnCallTeams: Lists all teams from Grafana OnCall with their details
• ListOnCallUsers: Lists all users from Grafana OnCall with their details or Get a specific user by the UserID or Username

Also this PR adds a "cloud test" against a specific testing instance (for now mcptests.grafana-dev.net)

Adding support for:

• alert groups
• shift swap requests
  depend on adding support for them to the client.
  For alert groups there is already an open PR which we are pushing forward at the moment.

Before merging we need to alter the github actions required to unblock merging
At the moment we require Test while we are gonna need three rules specific for unit, integration and cloud.

Nice, this looks like it will be super useful! I added a few comments inline.

Suggested change

	go test -v -tags cloud ./tools -run TestCloudOnCall
	go test -v -tags cloud ./...

[ioanarm]

👍 I need the path though ./tools as we have the mcpgrafana_test which checks the env vars.

[ioanarm]

I've separated completely unit tests, docker based integration ones and cloud so we now run three separate commands in git actions.
docker and cloud ones require env vars which are different in each case so having them both under the same command just complicated things for no reason.
three test categories with tags maybe make a bit more sense.

if it works 🙄

@sd2k Thanks for reviewing this :)
I think I covered your comments, let me know if there is anything else I can add/improve!

[sd2k]

LGTM! one very minor suggestion. I'll update the Ruleset to refer to the new CI jobs too.

[sd2k]

Ah the README will need updating to refer to the new make targets too.
