Additional JQL Functions to get the last sprint closed for an issue

Issue Summary

When a customer needs to get the last sprint for certain issue(s), it would be nice to have something like a previousSprint() or lastClosedSprint() function to retrieve this information and use it with other products, for example when running queries in Automation for Jira.

Steps to Reproduce

1. Go to the advanced issue search 
2. Switch the search to use JQL
3. Try to use the sprint functions documented here: Advanced search reference - JQL functions

Expected Results

• closedSprints()

• futureSprints()

• openSprints()

• previousSprint() or lastClosedSprint()

Actual Results

• closedSprints()

• futureSprints()

• openSprints()

Workaround

No workaround so far.
