Scout-apm

Added

Fixed
- Always return a tuple from ``filepaths``.
([Issue 737](https://github.com/scoutapp/scout_apm_python/issues/737))

Added

Fixed
- Return the full path for backtraces that are used by the core-agent and
APM product. The error stacktraces now prepend the SCM_DIRECTORY setting
if it has been set.
([Issue 723](https://github.com/scoutapp/scout_apm_python/issues/723))

Added

Fixed
- Avoid assuming Celery tasks will have a truth-y `delivery_info` property.
([Issue 731](https://github.com/scoutapp/scout_apm_python/issues/731))

Added
- Add `log_payload_content` to support logging the content of the message
being sent to either the core agent socket or the error service.
([Issue 724](https://github.com/scoutapp/scout_apm_python/issues/724))

Fixed

Fixed
- Only log warnings for ElasticSearch client method instrumentation
if no client methods were instrumented. Otherwise, log the issues at
the debug level. This avoids flooding logs when clients use an older
version of ElasticSearch.
([Issue 713](https://github.com/scoutapp/scout_apm_python/issues/713))
- Restore building wheels for python 3.4 and 3.5.
([Issue 584](https://github.com/scoutapp/scout_apm_python/issues/584))

Added

Fixed
- Avoid instrumenting PyMongo collection methods that were removed in v4.
([Issue 710](https://github.com/scoutapp/scout_apm_python/issues/710))
- When Celery `task_failure` signal has a string type for the `traceback`
parameter, use the `einfo.tb` to fetch the traceback.
([Issue 708](https://github.com/scoutapp/scout_apm_python/issues/708))
- Use urllib3 to post errors to Scout Errors API. Removes dependency on
requests library.
- Switch to a dict for the `request_params` away from a list of tuples.
