["Andrew Wong (Code Review)" <ge...@cloudera.org>]

Hello Kudu Jenkins, 

I'd like you to reexamine a change. Please visit

    http://gerrit.cloudera.org:8080/17370

to look at the new patch set (#4).

[txns][tools] tool to list transactions

This patch adds a tool to iterate through the transactions, listing their
states and interesting metadata. It includes some optional flags, shown
specified below:

$ ./bin/kudu txns list 0.0.0.0:8764 --show_hybrid_timestamps --min_txn_id=1 --max_txn_id=2
 txn_id | user  |   state   |     commit_ts (datetime)      |  commit_ts (hybrid timestamp)
--------+-------+-----------+-------------------------------+--------------------------------
 1      | awong | COMMITTED | Thu, 29 Apr 2021 22:12:53 GMT | P: 1619734373050242 usec, L: 0
 2      | awong | ABORTED   | <none>                        | <none>

I suspect we'll want to limit the output by default to only show open
transactions, but that will come as a follow-up change.
