nixos/{jira,crowd,confluence}: restart service on failure
In case of unexpected failures of the services - such as an OOM - it
shouldn't be necessary for an administrator to restart the service by
hand (which is usually sufficient). Instead, this should happen
automatically.

Also, I decided to increase the interval between restart attempts from
100ms[1] to 10s for a small grace period as suggested by several online
resources[2][3].
