Docs would be nice

Hi,

I just randomly stumbled upon this repo. Seems to be an interesting collection of various integration scripts, but it would be great if there were some docs, links to docs etc.

for example looking at this jira service management action executor
https://github.com/atlassian/jsm-integration-scripts/blob/master/jira-service-management/scripts/jec_action_executor.py
then trying to google '"mappedactionv2" jira service management' was something I naturally did, but nothing useful.

Thank you,
CJ

Start by reading jira-service-management/scripts/jec_action_executor.py and inventory the integration scripts and external references that need explanation. Clarify the documentation scope before editing; done means a newcomer can understand the referenced Jira Service Management behavior, including mappedactionv2, and find useful links.
