Rename the DRC Representatives role

Proposal: Change the name of the 5 elected DRC Representatives to Core Contributors (CC).

Rationale:

1. All members of the DRC community are representatives of DRC; all those with DRC in their wallets demonstrate and further the DRC ethos.

2. Not all members of the DRC community are contributors, however. DRC is a community-driven and governed ecosystem and requires the efforts of all it’s community in order to achieve great things. Some provide more contributions than others and should be given recognition as such. The term Core Contributors demonstrates the expected requirements for those that apply for the position.

The 3-month election cycle will begin anew on April, the current Reps felt that this name change would better highlight what is expected of any incoming applicants: passion, commitment, interest and tangible contributions.
