This reverts the configuration setting to disable plugin health checks, preferring instead to retain this functionality for advanced cases. In part, this was driven by the discovery that the health checks were failing on Windows, though that will be addressed separately.
Fixes: MM-16378
* simplify interval handling/logging
Also shutdown the job when plugins are altogether disabled.
* Move State property from activePlugin to PluginHealthStatus. env.activePlugins is now reserved for healthy running plugins.
* Add comments for function declarations
* Combine activePlugins and pluginHealthStatuses into a common structure, registeredPlugins
* Add check to see if plugin is active before deactivating it
* Make `Deactivate` set plugin status
* Add comment explaining the `registeredPlugins` map
* Give responsibility to set plugin disabled status upon deactivation back to `env.Deactivate`
* check if plugin needs to be deactivated before setting status
* introduce plugin health check
* implement plugin health check job
* add support for checking pid of plugin process and RPC ping, to determine a plugin's health
* implement restart policy with back-offs
* support "EnableHealthCheck" boolean from config file.
* add tests for supervisor.PerformHealthCheck() and shouldDeactivatePlugin()
* improve error handling. clean up if blocks to be more concise
