mgr/nfs: add --sectype flag to nfs export create functions
Fixes: https://tracker.ceph.com/issues/57404
Add the sectype argument, also for use as a CLI option, to the functions
that create nfs exports. NFS Ganesha can use the sectype configuration
option to decide what kind of security will be applied/required for
connection to an export.
NOTE: This option is only useful when Ganesha is configured along with
LDAP/Kerberos integration. Configuration of that integration is outside
the scope of these patches.

mgr/nfs: reformat long function calls to one line per arg
Using a hand rolled version of the long function call style similar to
that produced by the "Black" tool, put every argument to the
create_export function on a line of its own. This makes the code easier
to read and, importantly for an upcoming change, easier to add new
arguments.

mon/Monitor.cc: notify_new_monmap() skips removal of non-exist rank
Problem:
In RHCS the user can choose to manually remove a monitor rank
before shutting the monitor down. Causing inconsistency in monmap.
for example we remove mon.a from the monmap, there is a short period
where mon.a is still operational and will try to remove itself from
monmap but we will run into an assertion in
ConnectionTracker::notify_ranks_removed().
Solution:
In Monitor::notify_new_monmap() we prevent the func
from going into removing our own rank, or
ranks that doesn't exists in monmap.
FYI: this is an RHCS problem only, in ODF,
we never remove a monitor from monmap
before shutting it down.
--mon-initial-members does nothing but causes monmap
to populate ``removed_ranks`` because the way we start
monitors in standalone tests uses ``run_mon $dir $id ..``
on each mon. Regardless of --mon-initial-members=a,b,c, if
we set --mon-host=$MONA,$MONB,$MONC (which we do every single tests),
everytime we run a monitor (e.g.,run mon.b) it will pre-build
our monmap with
Now, with --mon-initial-members=a,b,c we are letting
monmap know that we should have initial members name:
a,b,c, which we only have `b` as a match. So what
``MonMap::set_initial_members`` do is that it will
remove noname-a and noname-c which will
populate `removed_ranks`.
Solution:
remove all instances of --mon-initial-members
in the standalone test as it has no impact on
the nature of the tests themselves.
When upgrading the monitors (include booting up),
we check if `peer_tracker` is dirty or not. If
so, we clear it. Added some functions in `Elector` and
`ConnectionTracker` class to
check for clean `peer_tracker`.
Moreover, there could be some cases where due
to startup weirdness or abnormal circumstances,
we might get a report from our own rank. Therefore,
it doesn't hurt to add a sanity check in
`ConnectionTracker::report_live_connection` and
`ConnectionTracker::report_dead_connection`.
