[SAC] Nominate Regina Obe to join SAC

[Sandro Santilli]

I'm nominating Regina Obe to join SAC for helping with
migrating interested projects from SVN to GIT
and other general maintainance tasks.

Regina is a PostGIS PSC member and manages our beloved
bots (jenkins, drone agent) and documentation.

Here's my +1, please cast your vote !
