in this change, instead of allocating the variables using `malloc()`,
we keep them in static variables, so that they can be accessed by
`OnExitManager` even if it is a static variable.
with this change, the memory leak reports for this source file go away.
* Fix incorrect syntax
* Use underscores for config options, like other ceph docs did
* Fix incorrect statement that crush_location_hook adds fiels; it replaces
* Explain `root=default host=HOSTNAME` is not set if `crush_location` is given
* Remove duplication across sections
* Point out that `root=default` is important
in BlueFS.test_shared_alloc, we keep the return value of
`fs.get_perf_counters()`, and deference it after umounting the fs,
but the `PerfCounters*` pointer returned from `fs.get_perf_counters()`
is destroyed in `BlueFS::_shutdown_logger()` which is in turn called
by `BlueFS::umount()`. so ASan points this out:

`mount()` calls, we get another instance of `logger`, query it for
the perf counter that we are interested, and compare the value
to see if it is unchanged.
