qa: make the xfstests tmp directories to be readable and excutable
The user namespace test case will excute some commands as the other
user. And the temporary direcotry now has the rx permission for
other users by default. The test then will fail otherwise.

test/osd-scrub-dump.sh: fix scrub chunk size
The test performs shallow scrubs, intentionally using small chunk
sizes to allow dump commands time to check specific details.
Following commit ffda64119fc6165cebffd0b26619ad47b13daf51
(PR#44749), shallow scrubs chunks are controlled by a separate
configuration parameter. This PR fixes the test to use the
correct parameter.
An additional minor change is an adjustment to the test loop sleep time:
it is now reduced to guarantee that a dump followed by a counter
increase will be performed in more-or-less the scrubs frequency.

tools, test/cli: add read balancer to osdmaptool
This commit adds the capability to balance reads on a
given osdmap with the osdmaptool. The user has the option
of performing a "dry run" of read balancing OR taking it a
step further and applying the results to a live cluster.
Performing a "dry run" would involve simply running an
osdmaptool command and inspecting the results.
The template for the command is:
`osdmaptool <osd map file> --read <file for command output> --read-pool <pool name>`
An example command a user might run is:
`osdmaptool om --read out.txt --read-pool default.rgw.control`
This commit also adds a `--vstart` flag that allows a user to print ceph
commands in the outfile formatted for a vstart cluster. An example command
a user might run is:
`./bin/osdmaptool om --vstart --read out.txt --read-pool default.rgw.control`
The out.txt file would contain ceph commands prefixed with `./bin/`.
The `--vstart` flag may also be applied to an `--upmap` osdmaptool command.
If the user wants to apply read balancing results from their dry run to a
live cluster, they may either manually apply the ceph commands from the out
file, or run `source <outfile>`.

osd: implement read balancer
This commit implements two functions:
1. calc_desired_primary_distribution
Based on the number of pgs in a pool and the pool's
replica count, we calculate the ideal number of primary
pgs that should be assigned to each OSD on that pool in
order for reads to be balanced.
2. balance_primaries
This is the overall algorithm used to balance reads (primary
pgs) in a pool. Based on the first function, we re-distribute
primaries on the OSDs in a pool so each OSD has the ideal
number of primaries. This is done without data movement.
