With the changes in MB-52632, a new option called disableMaxCount has been added for 7.5.0.
If disableMaxCount is not set (default in normal profile), both options:
Auto-failover after _ seconds for up to _ nodes are configurable through UI (as is the case today).
If disableMaxCount is set to true (as is the case by default in serverless profile), only the timeout can be configured i.e. Auto-failover after _ seconds is configuration (the limit up to _ nodes is not configurable).
There are also warnings that pop up when the maximum number of nodes that are allowed to fail over has been crossed - this warning should be suppressed if 'disableMaxCount' is true.
We may want to expose an option to allow the user to configure 'disableMaxCount'. The maximum number of cascading failover nodes (events) is restricted and if the user doesn't wish to impose a limit, they can do so by setting 'disableMaxCount' to true.
