Siavash Safi 2e0970e8d8 feat(dispatch): add start delay (#4704) ...

This change adds a new cmd flag `--dispatch.start-delay` which
corresponds to the `--rules.alert.resend-delay` flag in Prometheus.
This flag controls the minimum amount of time that Prometheus waits
before resending an alert to Alertmanager.

By adding this value to the start time of Alertmanager, we delay
the aggregation groups' first flush, until we are confident all alerts
are resent by Prometheus instances.

This should help avoid race conditions in inhibitions after a (re)start.

Other improvements:
- remove hasFlushed flag from aggrGroup
- remove mutex locking from aggrGroup
