* add jaeger support, link hot container & req span * adds jaeger support now with FN_JAEGER_URL, there's a simple tutorial in the operating/metrics.md file now and it's pretty easy to get up and running. * links a hot request span to a hot container span. when we change this to sample at a lower ratio we'll need to finagle the hot container span to always sample or something, otherwise we'll hide that info. at least, since we're sampling at 100% for now if this is flipped on, can see freeze/unfreeze etc. if they hit. this is useful for debugging. note that zipkin's exporter does not follow the link at all, hence jaeger... and they're backed by the Cloud Empire now (CNCF) so we'll probably use it anyway. * vendor: add thrift for jaeger

== DESCRIPTION:
Thrift is a strongly-typed language-agnostic RPC system. This library is the ruby implementation for both clients and servers.
== INSTALL:
$ gem install thrift
== CAVEATS:
This library provides the client and server implementations of thrift. It does not provide the compiler for the .thrift files. To compile .thrift files into language-specific implementations, please download the full thrift software package.
== USAGE:
This section should get written by someone with the time and inclination. In the meantime, look at existing code, such as the benchmark or the tutorial in the full thrift distribution.
