Add ability to set global tags in code (alternative to DD_TAGS)

[idanya]

Currently, the only way to set global tags that will be attached to all spans is by using DD_TAGS environment variable (unless I'm missing something). This is an issue for use cases where the service tags are loaded on runtime.

Possible mitigation: Setting the config/tracer with the global tags at runtime

version used: dd-trace-py 2.1.1

Is there an alternative available now? I sure would like to see this resurrected.
