Simon Murray d052e94b45 Fix TLS Race Connecting to InfluxDB 
Rather than leaving stale connections about we tried to poll for data coming in
from InfluxDB and timeout if it didn't repond in a timely manner.  This introduced
a race where the timeout triggers, a context switch occurs where data is actually
available and the TlsStream spins trying to asynchronously notify that data is
available, but which never gets read.  Not only does this use up 100% of a core,
but it also slowly starves the system of handler threads at which point metrics
stop being delivered.

This basically removes the poll and timeout, any TLS socket erros should be
detected by TCP keep-alives.
