This score works for pools in which the read_ratio
value is set.
Current limitations:
- This mechanism ignores osd read affinty
- There is a plan adding support for read affinity 0
in the next version.
- This mechanism works only when all PGs are full
- If read_ration is not set - the existing mechanism (named
fair score) is used.

Test cases for the read balancer which takes osd sizes into account.
Some balancing code refactoring and reorg for code that is used in
multiple tests

This commit adds calculation for desired primary distribution which
takes into account the osd size. This way smaller OSDs can take more
read operations (by adding more primaries) and the larger OSDs take less
primaries and the load of the cluater can increase. (This feature offset
a bit the weakest link in the chain effect under some conditions). In
order to calculate the loads correctly there is a need to know the
read/write ratio for the pool, and this commit assumes the read_ratio
parameter is available for the pool.

This parameter is used for better read balancing with non identical
devices.
- This parameter is controlled using the commands 'ceph osd pool set/get'
- This parameter is applicable only for replicated pools
- Valid values are integers in the range [0..100] and represent the
percentage of read IOs out of all IOs in the pool
- Value of 0 unsets this parameter and the value will be the default
value (this is the generic behavior of the command 'ceph osd pool
set'
- default value can be set by config parameter
`osd_pool_default_read_ratio`

These were probbaly introduced to workaround some sort of
resource overusage by the MDS during trimming, but now it
looks like they are not really neeeded, especially if we
introduce a dedicated thread for log trimming.

I ran into this failure once #54972 was merged. The test is validating
the error string returned due to the failed mount. There aren't any
return value checks - which is a _more_ important check. Generic error
string checks will fail once a (error) string is changed (typo, etc..).

`sync-labels` is defined as "Whether or not to remove labels
when matching files are reverted or no longer changed by the PR".
We should disable this in case someone manually adds a label,
so the label doesn't get removed.

Issue:
Currently, we are unable to create subvolume of same name in different
subvolume group
Fix:
We are validating only the filesystem name of subvolume
which is stopping the creation a subvolume of same name.
Added more granularity , by adding the subvolumegroup name.
