DRILL-5152: Enhance the mock data source: better data, SQL access
Provides an enhanced version of the mock data source. See the JIRA entry
for motivation, package-info.java for details of operation.
Allows tests to write queries of the form:
```
select id_i, name_s50 from `mock`.`employee_1K` ...
```
Where id_i is a field of random, uniformly distributed integers and
name_s50 is a VARCHAR column of width 50 of randomly generated strings. The _1K
suffix says to generate 1000 rows. The names are just for convenience, the
suffixes tell the mock data source what to generate.
Examples of use will appear in a later commit that includes a revised test
framework. Existing tests that use the physical plan version of the mock data
source work as before.
