[tools] ksck: Add information about replica counts to plain ksck output
This adds some information about replica counts on tablet servers to the
output of ksck when ksck is in PLAIN_* mode (i.e. not JSON output). In
PLAIN_CONCISE mode, it outputs a 5-number summary of the distribution of
replicas and lists any outliers:
Tablet Replica Count Summary
Statistic | Replica Count
----------------+---------------
Minimum | 1646
First Quartile | 3672
Median | 4075
Third Quartile | 4242
Maximum | 4600
Tablet Replica Count Outliers
Type | UUID | Host |
Replica Count
-------+----------------------------------+--------------------------------+---------------
Small | cc32936bc8594948a04fd4240da36aed | vc1304.halxg.cloudera.com:7050 |
1646
In PLAIN_FULL mode it outputs the replica count for every tablet server:
Tablet Replica Count by Tablet Server
UUID | Host | Replica

I also tested it against an empty cluster.
There's no unit tests added, just because our current testing setup for
ksck makes it really painful to add one for this, and it seemed easy
enough to check out manually. Probably, a follow up should straighten
out ksck-test to make testing ksck changes easier.
