mgr/cephadm: add a feature to examine the host facts to look for configuration/compliance problems
Once the host facts are part of the mgr/cephadm cache, he idea is to periodically check the host cache to look for anomalies. Any anomaly woul dbe flagged as a mgr healthcheck WARN alert.
These are the kinds of checks that could be implemented;
- OS version consistency
- Support consistently configured
- Security policy (SELINUX, AppArmor enabled) is consistent
- cluster network and public network using consistent * network connection speeds * interface MTU size * dedicated/shared interfaces
The longer term goal would be to allow these checks to be enabled/disabled from the UI.
