[metastore] Provide create table as Kudu option

https://issues.cloudera.org/browse/IMPALA-2848
https://kudu.apache.org/docs/quickstart.html

Hue's create table wizard could provide an easy way to create a Kudu table from a file or nothing (#2 and #1).

Attributes to provide with good defaults / modifiable by the user:
PK, HASH(), # of buckets

1. Create table manually
2. Create table from a file
   1. Create regular Impala table, CTAS as Kudu, delete regular table

Ideas of follow-ups?

1. Create table from another table?
2. Hint that the table supports updates
3. Support updating cells like in Search or Jira

CREATE TABLE my_first_table 
(
  id BIGINT,
  name STRING,
  primary key (id)
) 
PARTITION BY HASH PARTITIONS 10
stored as kudu
