We need to keep track of the monotonic clock deltas between peer OSDs in
order to be able to exchange timestamps across messages. We need an
upper and lower bound on this delta, depending on the context where it is
used.
We can use the existing ping messages to get this by assuming that a ping
message is sent instantly to get a bound, and to share our delta in a
follow-up reply to share the other bound. The ping sender will get both
bounds with a single ping + ping_reply exchange. The ping receiver will
get the delta value from the next round's ping.
Include up_from in the ping messages to ensure we don't mix up different
instances of the same OSD.

* use the default `TOX_PATH` parameter instead passing it explicitly,
as it is always `${CMAKE_CURRENT_SOURCE_DIR}`
* drop the code to guess the tox envs in `run_tox.sh`, and always pass
them explicitly in CMake script using the `--tox-envs` argument.

so we can prepare the venv for tox with `make tests`. and it's optional,
as run_tox.sh will check for it and setup a venv if it's not around.

otherwise when we destruct `TestObjectRecorder::Handler::lock` or
`journal::JournalRecorder::m_object_locks`, it/they would be still

`PG` print details info in the prefix of logging messages if the PG is
being locked by current thread. but `ceph::mutex` is an alias of
`std::mutex` in non-debug mode, so neither `mutex::is_locked_by_me()` nor
`mutex::is_locked()` is supported in non-debug mode. to continue supporting
this feature, `PG::locked_by` is added to memorize the thread id of the owner
of the lock.
