Prepared DBLIB for multi-verndor JDBC Driver
Changes made: 1. removed hardcoded JDBC driver's name and made it a property. 2. Optimized connection pool initialization 3. Removed unused factories. Change-Id: Id1d1868f7f1a6ae5a0429a97403042a8f6ee78d3 Issue-ID: CCSDK-92 Signed-off-by: Rich Tabedzki <richard.tabedzki@att.com>
