os/bluestore: fix unexpected ENOSPC in Avl/Hybrid allocators.
Avl allocator mode was returning unexpected ENOSPC in first-fit mode if all size-
matching available extents were unaligned but applying the alignment made all of
them shorter than required. Since no lookup retry with smaller size -
ENOSPC is returned.
Additionally we should proceed with a lookup in best-fit mode even when
original size has been truncated to match the avail size.

crimson/os: fix use-after-free in AlienStore::get_attr().
The `FuturizedStore` interface imposes the `get_attr()`
takes the `name` parameter as `std::string_view`, and
thus burdens implementations with extending the life-
time of the data the instance refers to.
Unfortunately, `AlienStore` is unaware that prolonging
the life of a `std::string_view` instance doesn't prolong
the data memory it points to. This problem has manifested
in the following use-after-free detected at Sepia:

crimson/os/alienstore: create tp in AlienStore::start()
thread pool is not needed until AlienStore::start(). with this change,
we are able to tell if the AlienStore is actually started or not in
AlienStore::stop().
as seastar::sharded<Service> start a service in two phases:
1. construct the shard instances
2. actually start them
and it stops a service in a single shot, which both stops the services
and destructs the service instance(s).
so we have to implement a proper stop() method for services whose
start() might not be called after its instance is created by
seastar::sharded<Service>::start() in case of error handling or if
we just don't want to call start().
to ensure we can skip the steps to clean up the stuff created by
start(), we need to have a flag in the sharded service, because
AlienStore is a member variable of OSD, and when we do mkfs, AlienStore
is not start()'ed, and as explained above, we have to call OSD::stop()
to ensure OSD instance is destructed properly. but OSD::stop()
calls store->umount() and store->stop() unconditionally. these methods
in AlienStore rely on a functional thread pool.
fortunately, we don't need to call these methods if the store is never
mounted or started. in a case of failed "mkfs", store is not mounted at
all but the store and osd instances are created.
so, in this change, thread pool is created in AlienStore::start(), and
we will use it to tell if AlienStore is started or not in the following
change which makes the related method no-op if AlienStore is not started
yet.
also, postpone the creation of `store` until in AlienStore::start(), so
we don't need to destroy it in the dtor of AlienStore. otherwise,
BlueStore::~BlueStore() would need to reference resources which are only
available in alien threads, but when OSD::~OSD() is called, we are in
seastar's reactor.

crimson/osd/main: catch exception thrown in the async() call
* use seastar::app_template::run() instead of
seastar::app_template::run_deprecated() for returning int,
instead of returning `void`. so the application can return
int explicitly in the continuation passed to run(). more
readable this way.
* wrap the all the block in run() in a giant try-catch block,
so the exceptions thrown by the startup code can be captured
and handled.
* do not capture the exceptions individually, in the try-catch
block anymore. the outer catch block takes care of them.
this change improves the error handling when crimson-osd launches.
with the recent support for async rbd operations from pacific+ when an
older client(non async support) goes on upgrade, and simultaneously
interacts with a newer client which expects the requests to be async,
experiences hang; considering the return code for request completion to
be acknowledgement for async request, which then keeps waiting for
another acknowledgement of request completion.
this if happens should be a rare only when lockowner is an old client
and should be deferred if compatibility issues arises.

Previously we allowed the host.addr to be a DNS name (short or fqdn).
This is problematic because of the inconsistent way that docker and podman
handle /etc/hosts, and undesirable because relying on external DNS is
an external source of failure for the cluster without any benefit in
return (simply updating DNS is not sufficient to make ceph behave).
So: update any non-IP to an IP as soon as we start up (presumably on
upgrade). If we get a loopback address (127.0.0.1 or 127.0.1.1), then
wait and hope that the next instance of the manager has better luck.
