Set thread title

[jkohen]

This helps understand thread usage with commands like top -H and ps -e -T

Before this change the thread name shows up as thread.rb:70. After, it may show up as whatever title was given. The exact behavior will depend on the implementation of Ruby's native_set_another_thread_name.

It looks like the Thread.name= method was introduced in Ruby 2.3.0, hence the build failures. Any suggestions on how to get that to work? We are investigating what is causing a high number of threads in fluentd, which affects the memory usage in GKE.

FWIW, Ruby 2.3.8 is already EOL and Travis doesn't seem to be testing against 2.3.x. When are you planning to stop supporting 2.1.10?

How about thread.name = title.to_s if thread.respond_to?(:name) ?

Cool, that seems to have worked! Thanks, I'm all new to Ruby.
