```
* rename request to response, isort and black fixes
* Log exception details
* Add status code to success log, reformat log
* new syntax for response
* changed info to debug
* fix rest_command when server is unreachable
When a server doesn't exist, the connection fails immediately, rather
than waiting for a timeout. This means that the async handler is never
reached, and the request variable never filled, yet it's used in the
client error exception handler, so this one bugs out.
By using the command_config, we avoid using the potentially unassigned
request variable, avoiding this problem.
This patch makes scripts work that have a rest_command in them which
fails due to a server being offline.
* render template_url
instead of printing the template object
* fix formatting
* fix format using black
* only render url once
* blacken...
