Create IBM ConfigFile base directory

The ConfigFile upload fails when the /var/lib/obmc directory is not
available at BMC

This commit changes the base directory to /var/lib/bmcweb
The subdirectories for the configfiles and locks
are created under this new path

Migration strategy of this directory and files:
 This is IBM only feature, compiled under the IBM_MANAGEMENT_CONSOLE flag
 There is no system out yet which is running this code
 Internal IBM stake holders are in agreement with the changes

Tested by :
  1. Tested configfile upload on a BMC where the base directory is not
available
  2. Tested the configfile upload on a factory BMC. Verified it creates
     the base directories and the upload is successful
  3. Tested the configfile usecases for delete and delete-all
  4. Tested the acquire-lock functionality
  5. Ran lock unit test successfully
