[Epic] async-profiler support

[andrewazores]

Describe the feature

async-profiler is, well, a profiler for HotSpot JVMs. It's very powerful and it can output its data in the JFR binary file format, so it seems a natural fit that Cryostat should also be able to at least gather these files if a target JVM is determined to have async-profiler loaded as an agent. This would be somewhat similar to the support we currently have for the JMC bytecode instrumentation agent.

Any other information?

• Detect if async-profiler is present on target
• Readonly view for async-profiler data
• Dynamic updates for async-profiler state (ex. remote configuration)
