For a future PR: perhaps move this part to a different app_action?

Yeah, I agree. Plus, one day we should also decide if we want to enable/disable event source for capture files too (A single capture file can potentially contain events from more than one source).

What this PR does / why we need it:
This PR introduces a new cmd line option
--enable-source=XXXthat is dual to the already-existing--disable-source=XXX. Both of them are opt-out: it is up to Falco to choose the default enable event sources depending on the provided configuration. So far, only one can be enabled per time (eithersyscall, or a plugin-based one).The semantic of
--disable-sourceis of disabling event sources selectively starting from the set of the ones enabled by Falco by default. On the opposite,--enable-sourceerases the Falco default enable set and allows enabling sources selectively.The feature of selecting a custom set of event sources has been introduced in the regression test suite too (
falco_tests.py). Tests relying on plugins have been updated accordingly.Which issue(s) this PR fixes:
Special notes for your reviewer:
For the current setup, this is sort of a huge no-op. However, this introduces preliminary work for #2074.
