David Yat Sin 295acf6b27 PC Sampling: API to list supported configurations
Add new PC Sampling API to list the supported PC Sampling methods and
options on a specific agent. If there is already a PC Sampling session
active on this agent, the list of methods returned will be reduced to
methods that can be run simultaneously with the current active session.
