This command is used to add a new alert to Alertmanager.
To add a new alert with labels:
amtool alert add alertname=foo node=bar
If alertname is omitted and the first argument does not contain a '=' then it will
be assumed to be the value of the alertname pair.
amtool alert add foo node=bar
One or more annotations can be added using the --annotation flag:
amtool alert add foo node=bar \
--annotation=runbook='http://runbook.biz' \
--annotation=summary='summary of the alert' \
--annotation=description='description of the alert'
Additional flags such as --generator-url, --start, and --end are also supported.
