This will allow to match and compare the DTrace probes with SPDK traces
as they'll be using the same source for the timestamps.

The traces are tracking the lifecycle of a poll group: creating it,
adding and disconnecting qpairs, and finally destroying the group.

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!
