osdc: Add SplitOp capability to Objecter
This will provide the ability for Objecter to split up
certain ops and distribute them to the OSDs directly if
that provides a preformance advantage.
This is experimental code and is switched off unless the
magic pool flags are enabled. These magic pool flags were
pushed in an earlier commit in the same PR.

osdc: Remove unused con parameter from Objecter::_calc_target()
This parameter is not used by the _calc_target code. It is being
removed just to clean up the code, as we are making some changes
to _calc_target in later stages of the split io PR.

osdc: Interface to submit IO with ASIO Post.
For direct read failures, the locking is such that we cannot
immediately send a new IO without deadlocking. This new interface
allows an op to be sent as an asio post.

osd: Implement sync reads and sparse reads for EC for direct reads
Sparse reads for EC are simple to implement, as the code is essentially
identical to that of replica, with some address translation.
When doing a direct read in EC, only a single OSD is involved and
that OSD, by definition is the only OSD involved. As such we can
do the more performant sync read, rather than async read.

osd: Generalise can_serve_replica_read for consumption by EC.
The can_serve_replica_read() function is called by replica to determine whether there are
any uncommitted writes. If such writes exist, then the system will reject the IO to avoid
the risk of reading data from a write which may yet be rolled back.
The same code is going to be useful for EC direct reads.

osd: Replace unused EC offset translation function with useful one.
The old chunk_aligned_shard_offset_to_ro_offset was not only unused, it
didn't actually have the correct logic. We replace it here with similar,
but more useful function that will be used in sparse reads for EC

osd: Introduce pool flag for "split IO" and Plugin flag for "direct read"
These flags will currently behave as follows:
1. The pool flag is never set, unless by a user with the osd_pool_default_flags
config option.
2. The pool flag will be removed for EC pools where the plugin does not support
direct reads.
3. Replica pools will never remove the flag.
The intention is to eventually invert this logic and allow split IOs upon
upgrade to Umberella in this same function.

mgr/dashboard: Carbonize the Change Password Form
Fixes https://tracker.ceph.com/issues/73193
- using carbon based stylings, typography and components
- used grid layout for form arrangement
- breadcrumb is slightly off, which needs to be fixed by applying grid layout to the app shell

qa/suites/rados/encoder: exclude ceph-osd-* when installing LTS releases
In a37b5b5, the ceph-osd-classic and ceph-osd-crimson packages were
added to qa/packages/packages.yaml. The "install" task uses this file as
the default package list for all branches, including LTS releases like
Reef.
However, a37b5b5 only exists in the main branch and won't be backported
to LTS branches. This causes installation failures in the rados/encoder
test suite, which verifies forward compatibility by installing LTS
releases and testing whether they can decode the latest corpus.
Exclude ceph-osd-classic and ceph-osd-crimson from LTS installations to
ensure the test suite can successfully install ceph-dencoder, which is
required for the interoperability tests.

qa/clusters/crimson: increase reactors in fixed-1 cluster
Issue: Various different tests were failing randomly due to slow
ops. There was no common ground between them, it was happening
across differnet object stores (seastore and bluestore) and
across different tests.
Cause: Since this is happening quite randomly, this is likely
happening due to low reactor count.
Solution: We are opting the solution to increase reactors used
for testing. I've increased them to 3 from the initial 2 value.

mgr/smb: Disable posix locking in share definition
The prerequisites for supporting durable handles[1] in Samba include
disabling the mapping of POSIX locks, as well as setting the `kernel
oplocks` and `kernel sharemodes` parameters to disabled. Currently
this configuration is hard‑coded, but in the future it could be made
conditional and combined with other settings to enable persistent
handles on continuously available shares.
