[alerting] Adds an alertServices mock and uses it in siem, monitoring…

… and uptime (elastic#63489)

Work on elastic#61313 has revealed that we don't have amock for AlertServices, which creates coupling between us and any solution depending on us, which makes it harder to make changes in our own code.

This PR adds mocks and uses them in SIEM, Monitoring and Uptime, so that we can make future changes without having to change outside solutions.
