Significant changes

Local Route Emitters

• route-emitter in tcp mode should apply events cached during syncing
• route-emitter should not re-emit optimistically removed actual LRPs during sync cycle

De-Consuling Locks (Experimental)

• As a Locket client, I expect the locket repository to contain documentation about the locket API
• As a CF operator, I expect the deployment to fail if the locket-enabled BBS or auctioneer cannot connect to or authenticate to the locket service successfully

Container Networking Support (Experimental)

• As a Diego operator, I expect to be able to opt the route-emitters into broadcasting instance IPs and ports in HTTP and TCP route registrations so that the routers can connect to them directly (in flight)

Declarative Health Checks (Experimental)

• As a BBS API client, I can specify HTTP and TCP healthchecks on LRPs declaratively so that I avoid specifying the healthcheck implementation

Component Logging and Metrics

• As a Diego operator, I expect the BBS to emit its request latency only periodically, instead of on every request
• cloudfoundry/lager #25: add lgctx package

Dependencies

• As a Diego contributor, I would like etcd listed as a dependency in CONTRIBUTING.md while our test suite depends on it

Cleanup

• Remove export GODEBUG=netdns=cgo workaround from diego ctl scripts
