Steps to reproduce:

1. Configure 2 nodes Server cluster with PCS(Corosync/Pacemaker) with external database cluster which has RW/RO roles.
2. Enable Native HA to have ability to stop on RO database, while Native HA will not be used at all.
3. Make local to the node DC database Read Only.

Result:
After ZBX-23685 HA manager keeps running endlessly preventing from switchover, Server is not stopped and PCS (Pacemaker/Corosync) is not triggered.

Expected:
Behaviour should be configurable (what to do on RO database: stop or continue attempts) and mostly outside of the Native HA configuration, since currently Native HA cannot do VirtualIP, database quorum consistency checks, own quorum, and the only useful feature for complex cluster was an ability to stop the service on RO database. Also Server cannot provide any of the status pages, like do other tools, so interoperability of the PCS/haproxy is limited or requires custom scripting.
