Also add scripts/bpf/nvmf.bt to enable and log these
probes.
This patch also adds a script that can generate
a bpftrace script snippet with string maps for
needed enumerations (currently nvmf_tgt_state and
spdk_nvmf_subsystem_state). This allows us to
dynamically generate this from the source code, and
can be extended for other enums we may want to
add in the future.
Thanks to Michal Berger for converting my original
gen_enums.py script into gen_enums.sh!

This UT was not working as intended, and was covered by

A single _reactor_run() iterates over all active pollers.
If at least one returns busy, so does the thread.
Thread load at the begining of UT is not 'low', but 100% busy.
To emulate loads outside of the 100% busy/idle, multiple
spdk_thread_polls need to be exectued.
As such to keep this case simple, the busy poller is removed.
