KUDU-3164: Add table comment support to Kudu
This patch adds the basic plumbing for table comments,
synchronizing comments with HMS both using the
notification log listener and via tooling, and setting the
comment on CREATE TABLE and ALTER TABLE requests in
the C++ client.
The maximum comment length is 256 characters by default
which aligns with HMS/Apache Impala maximum comment
lengths, but it's configurable with the
max_table_comment_length flag.
Supporting this in the Java and Python clients, and backup
and restore jobs will come in follow on patches.

> Project: Kudu
> Issue Type: New Feature
> Reporter: Quanlong Huang
> Assignee: Grant Henke
> Priority: Critical
>
> When Hive Metastore Integration is enabled, tables are created by Kudu.
> However, Impala can't pass the table comment since the CreateTable API
> doesn't have arguments for table comments, which results in lossing the table
> comments.
