* feat(cmapi): add read_only param for API add node endpoint
* style(cmapi): fixes for string length and quotes
Add dbroots of other nodes to the read-only node
On every node change adjust dbroots in the read-only nodes
Fix logging (trace level) in tests
Remove ExeMgr from constants
Fix tests
Manually remove read-only node from ReadOnlyNodes on node removal (because nodes are only deactivated)
Review fixes (mostly switching to StrEnum analog before py3.11, also changes in ruff config)
Read-only nodes are now called read replica consistently
Don't write hostname into IP fields of the config like PMSx/IPAddr, pmx_WriteEngineServer/IPAddr
We calculate ReadReplicas by finding PMs without WriteEngineServer
In _replace_localhost, replace local IP addrs with resolved IP addrs and local hostnames -- with the resolved hostnames.
ModuleHostName/ModuleIPAddr is kept intact.
Keep only IPv4 in ActiveNodes/DesiredNodes/InactiveNodes
feat: add mock DNS resolution builder for testing hostname/IP mappings
* Fix _add_node_to_PMS: if node is already in PMS, save it to existing items to not miss it during the reconstruction of the list
* Make tests independent from CWD
Fixed for _add_Module_entries
Fixed node removal and tests
Fixes for node manipulation tests
