ADMIN: Add the ability to view DB_LOOKUP settings for each cell

Each cell in the i2b2 hive has a DB_LOOKUP table that contains the information it needs to connect to the appropriate database for that cell and project. Currently, there is no easy way to view or edit the information in these tables. This enhancement will allow administrators to view and edit the database settings defined for each cell.

As part of this enhancement, 3 new pages have been created. These pages will contain the following fields:

1. Name
2. DB Schema
3. JNDI Data Source
4. DB Server
5. Project Path
6. Owner ID
7. Tooltip
8. Comment

The fields on the pages are equivalent to the following columns in the DB_LOOKUP tables:

1. Name = C_DB_NICENAME
2. DB Schema = C_DB_FULLSCHEMA
3. JNDI Data Source = C_DB_DATASOURCE
4. DB Server = C_DB_SERVERTYPE
5. Project Path = C_PROJECT_PATH
6. Owner ID = C_OWNER_ID
7. Tooltip = C_DB_TOOLTIP
8. Comment = C_COMMENT

                             - The page will close and return to the DB Lookup List page.

WARNING: The Delete button will remove the database connection settings from the DB_LOOKUP table so you need to make sure you are deleting the correct one.
 

New Services
Several new services were developed in order to accommodate this new feature.

     * getALLDBLookup: retrieves all the database configurations for that cell
     * setDBLookup: saves new database entries into the appropriate DB_LOOKUP table
     * getDBLookup: retrieves the configuration of a single database connection
     * deleteDBLookup: deletes the database configuration from the appropriate DB_LOOKUP table

Information about these new services can be found in CORE-218.
