What does this PR do?

This PR adds a process_tags field to the telemetry Application struct. This tag can be set during configuration or later (when the process_tags are acquired).

Motivation

dd-trace-php needs to be send the process_tags for its telemetry according to this RFC.
It is important to note that the tracer will set the configuration of its sidecar before we can retrieve the process_tags. That's why I created a function specifically to set the processs_tags.

How to test the change?

A PR will be opened soon in dd-trace-php to test the functionnality.
