Added allocation basis quantity REST API and related regtests

[jmcameron]

Updates for cost center analysis

• Added REST API for cost center allocation basis quantity table
• Added regression tests for allocation basis items
• Added regression tests for allocation basis quantity items
• Added a few more allocation basis items
• Other updates related to the Fee Center -> Cost Center updates

TESTING

• In Cost Center Management > Cost Centers > Menu > Allocation bases, note the new predefined items
• Test adding/editing/deleting allocation basis items
• In the Cost Center Management > Cost Centers page, try editing one of the centers and choosing one of the new predefined basis items

NOTE: Although my testing with bhima_test (eg, yarn build:db) seems to work, I have not tested this with a production database and the migration process. We need to verify that this works (or update the migrate.sql file as appropriate).

All tests passed with success and it works as expected

@jmcameron could you update this branch with the latest version of bhima/master, and then I will merge it
