Previously, when creating a new database, the CatalogOpExecutor would
create an HMS Database object, issue the HMS createDatabase call, and
then create a Catalog entry from that same Database object. The
resulting Catalog entry would be missing certain fields that are
auto-created by the HMS itself, most importantly the location field.
The code for CTAS seems to have contained a workaround for this issue
ever since catalogd was first introduced: rather than using the location
stored in the Db object, it would re-fetch the Database from HMS.
Now that this is fixed, that workaround could be removed and some code
simplified.
A new test verifies that a newly-created database has the appropriate
location, and existing CTAS tests verify that functionality didn't
regress.

Before this commit it was quite random which DDL oprations
returned a result set and which didn't.
With this commit, every DDL operations return a summary of
its execution. They declare their result set schema in
Frontend.java, and provide the summary in CalatogOpExecutor.java.
Updated the tests according to the new behavior.

Adds new parametrization to the unique database fixture:
- num_dbs: allows creating multiple unique databases at once;
the 2nd, 3rd, etc. datbase name is generated by appending
"2", "3", etc., to the first database name
- sync_ddl: allows creating the dabatases(s) with sync_ddl
which is needed by most tests in test_ddl.py
Testing: I ran debug/core and debug/exhaustive on HDFS and
core/debug on S3. Also ran the test locally in a loop on
exhaustive.

This is the first in a series of patches to clean up test_ddl.py
Summary of changes:
- Break up test_create() and corresponding .test files into:
* test_create_database()
* test_create_table()
* test_create_table_like_table()
* test_create_table_like_file()
* test_create_table_as_select()
- Merge test_nested() into the tests above
- Move a test into test_hms_integration.py
- Add a new test_ddl_base.py as base class for DDL tests.
The plan is to split up test_ddl.py into several smaller
.py files in subsequent patches.
Testing: I tested test_ddl.py and test_hms_integration.py on
exhaustive locally as well as in private builds on all filesystems.
