Services don't resume sending spans after an agent outage

[lopezzlaura]

Jaeger agent outage may occur and when they do, the RemoteReporter is not able to send anything as long as agent is down. When restarting the agent, the reporter should be able to resume and traces/spans to be collected again without having to manually redeploy every instrumented service.

Problem

When restarting Jaeger agent our services cannot send spans for a period of time and when the agent comes back, services aren't able to reach it so spans remains unsent. The issue has already been addressed several times, I saw a recent comment about it in this MR : #726 (comment)

Proposal

Issue is already patched in the go client : jaegertracing/jaeger-client-go#520, could we also have a similar support on the Java client ?
