Trigger buildTeam operation if server transition from unhealthy -> healthy

[sfc-gh-ahusain]

DataDistribution actor helps in building teams as server count changes
(add/removal), however, it is possible that total_healthy_server count
is insufficient to allow team formation. If happens, even healthy server
count recover, the buildTeam operation will not be triggered.

Patch proposal is to trigger checkBuildTeam operation if server
transitions from unhealthy -> healthy state. Incase system already
has created enough teams (desiredTeamCount/maxTeamCount), the operation
incurs a very minimal cost.
