Refactor code to facilitate other changes. Keeping the refactored code in different patch for ease of review. This patch mainly consolidates the keys that are referenced together most of the time in reference to providernet extension. By doing this, the subsequent changes are less repetitive and makes the code little cleaner as well. Change-Id: Idc0648d5c4688c8f797cc5427b71c2a3919ce722 Related-Bug: #1333475
