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.

the Reef dev freeze. This commit is intended to
lessen the load on the teuthology queue as we
test final patches for Reef, but should be reverted
after the dev freeze.

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>`.
