* 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

Using Thrift with PHP
Thrift requires PHP 5. Thrift makes as few assumptions about your PHP environment as possible while trying to make some more advanced PHP features (i.e. APC cacheing using asbolute path URLs) as simple as possible.
To use Thrift in your PHP codebase, take the following steps:
#1) Copy all of thrift/lib/php/lib into your PHP codebase #2) Configure Symfony Autoloader (or whatever you usually use)
After that, you have to manually include the Thrift package created by the compiler:
require_once 'packages/Service/Service.php'; require_once 'packages/Service/Types.php';
Dependencies
PHP_INT_SIZE
This built-in signals whether your architecture is 32 or 64 bit and is used by the TBinaryProtocol to properly use pack() and unpack() to serialize data.
apc_fetch(), apc_store()
APC cache is used by the TSocketPool class. If you do not have APC installed, Thrift will fill in null stub function definitions.
