[Pinot 1.2.0 UI] No support for "database" construct from UI

[ajeydudhe]

Problem statement

Pinot 1.2.0 supports database constructs as mentioned here. However, the UI does not allow creating a table using a database or querying a table within a database.

Steps to reproduce

• Launch the Pinot 1.2.0 controller UI.
• On the table screen there is no option to create table within a database.
• Create a table using REST API passing the database http header.
• Now, try to query above table using the UI passing the database as below:

  SET database='testDb';
  select * from myTable limit 10;

• Above query gives following error:

  Database name 'testDb' from table prefix does not match database name 'default' from header
