[wasp-agent] Add relevant alert and metric to detect duplicate wasp-agent deployment (#3705)

* Remove RWX filesystem mode requirement from vmStateStorageClass

Signed-off-by: Samuel Albershtein <salbersh@redhat.com>

* alerts: allow to use external runbook URL

currently the runbook URLs are consolidated under common
URL prefix that can be defined using the RUNBOOK_URL_TEMPLATE
env var, of fallback to the default which is from kubevirt domain.

with this change the alert author can opt-in for custom runbook
URL when the runbook is hosted on specific organization repository

* add alert for detecting duplicate wasp-agent deployment

In an upgrade scenario it can happen that duplicate wasp-agent
deployment can appear, since previous wasp-agent deployments
were manual and in a different namespace.
Therefore in order to make sure the user is aware of it we
are adding an alert which will rely on the a metric of memory
overcommit percentage and presence of wasp namespace.
