FLUME-3020. Improve HDFS Sink escape sequence substitution
When using escape sequences, the current code will call InetAddress
for every event which results in a huge impact to performance.
This patch fixes that issue by caching the local host in a static variable.
We can do this because there is zero chance the local host will change for a
life of a JVM.
