upgrade thrift to v0.14.1 in jaeger exporter

[kjschnei001]

With CVE-2020-13949 in mind, this PR upgrades the version of the vendored thrift library in the jaeger exporter from v0.13.0 to v0.14.1. It was not super clear to me why the thrift dependencies were packaged in this way, but I did my best to adhere to the established patterns as best I could, with respect to how the libraries were packaged into the exporter.

The thrift code was incorporated from a vendored version of the v0.14.1 library and I used thrift version 0.14.1 to auto-generate the jaeger-specific libraries from the jaeger-idl, modifying it only to establish new dependency paths within the opentracing project itself.

This shouldn't have dependencies under exporters/trace/jaeger/vendor/. The thrift dependency was manually 'vendored' under exporters/trace/jaeger/internal/third_party to avoid issues arising from attempting to use vendor/ in a library package. See #1548 and #1551 for some context on why it was done.
