Is your feature request related to a problem? Please describe.

Using the Agent in a docker container with read-only filesystem no new extension files are added after startup. Agent monitors extensions folder using FileSystemWatcher that starts a dedicated thread.

Feature Description

Configuration option to disable FileSystemWatcher from watching extensions folder in InstrumentationWatcher

Additional context

Each FileSystemWatcher creates dedicated thread. This would provide a way to reduce the number of threads (and inotify instances) used by the application for file watchers in case instrumentation changes are not required after startup.

Priority

Nice to Have
