* Add fromAlert

* Fix tests, move logger and context to struct

* Add instrumentation for processing response

* Move log for sending request closer to sending request

* Update

* Fix logging, improved messages, fix printing of queries

* Update log text

* Fix tests

* Fix lint

* Update logging to follow our guidelines

* Remove key-value pairs from logs that are going to be passed from instrumentation
