GA release v3.0.3

Changes since last release: v3.0.2...v3.0.3

See detailed announcement: orchestrator 3.0.3: auto provisioning raft nodes, native Consul support and more

Noteworthy:

• orchestrator/raft auto provisioning nodes: With 3.0.3 the failed node can go down for as long as it wants. Once it comes back, it attempts to join the raft cluster. A node keeps its own snapshots and its raft log outside the relational backend DB. If it has recent-enough data, it just needs to catch up with raft replication log, which is acquires from one of the active nodes. If it went down for a substantial amount of time, or is completely wiped out, the node gets, and bootstraps from, a valid snapshot from one of the active nodes.
• Key-Value support for master discovery: orchestrator will write to KV stores (Consul supported at this time) clusters' master identities. It will update KV upon failover.
• Web UI improvements: graceful promotion, mater takeover, silent mode
• More.
