Commit bd37d601d36bcf51c595baad52b5d24b5e20d684 in kudu's branch refs/heads/master from Abhishek Chennaka

[backup] KUDU-3183 Add --newDatabaseName and --removeImpalaPrefix 
options to restore job

While Kudu does not have a notion of database, usually the full
table name is stored as <database>.<tablename> on kudu side. (NOTE:
database name is optional). Using the options in this patch users
can change the existing database name of the table or add a new
database name to the table i.e. the prefix to the '.' in the full
tablename as well as remove impala prefix for the tables which
are being restored.

1.--newDatabaseName : Use this option to specify the new database
name for the restored table. This will overwrite any existing
database and if there is no existing database, a new database will
be added to the table name. Will not affect "impala::" prefix.
E.g: Adding database name "newDB" to the tables impala::default.test,
impala::test, default.test, test will result in the table names
impala::newDB.test, impala::newDB.test, newDB.test, newDB.test .
This will not affect the existing/source tables.

2.--removeImpalaPrefix : If enabled, this option will remove the
“impala::” prefix, if present from the restored table names. This is
advisable if tables are backed up in Kudu clusters without HMS
integration and being restored to Kudu clusters with HMS integration.

> The Kudu restore job has a `tableSuffix` option that is useful for slightly changing the name of a table on restore, but it could also benefit from a `tablePrefix` option. This would be especially useful as a way to append a database to a table name when restoring to an environment with HMS sync enabled.
