Description

This PR adds a public API for consumers of dd-trace-py to start the crashtracker. Previously, crashtracking was only enabled when an application is run with ddtrace-run.

Testing

Unit test using the public API

Risks

None

Additional Notes

There is no reason for customers to use this at the current moment, as Errors intake is not GAed yet.
