Provide an API for the Calling Application to set a database table life-span
priority on specific database tables.

When the upper limit on the database size is reached (see Bug #2673), the Data
Manager Library will free up space by reducing the number of cached data tables
in the database based on a "least used" removal algorithm. However, the Calling
Application should be able to protect specific tables from removal by setting
them as high priority. This is a boolean setting, either a table is protected
from removal or it isn't.

This task supports Use Case #6 in the Data Manager Library UML documentation.
