Change state machine tag key from DD_XYZ to xyz

[lym953]

Background

#552 sets DD_ENV, DD_SERVICE and DD_VERSION tags on the state machines.

Motivation

From the "custom" approach of instrumenting a state machine, we should set env, service and version, not the DD_XXX ones.

What does this PR do?

Makes plugin set env, service and version tags on the state machine instead of the DD_XXX ones.

Testing Guidelines

Passed the touched tests.

Additional Notes

Need a review from Cloud Tracing team, who, as the downstream consumer, should know what tags should be set here.
