[Story] Smart Triggers from file/resource

[andrewazores]

Another avenue for users to define smart triggers would be some configuration file(s) loaded at Agent startup. The file contents would use the same syntax as the agentmain string arguments, but perhaps could be either comma-separated or newline-separated. The Agent could look for such a configuration file as a classpath resource with a default name, or perhaps there could also be a configuration option like cryostat.agent.smart-trigger.config-files that defines a list of filesystem paths that should be read and parsed, or both, etc.
