Add time tracking stats to issue directly from the board
Problem to solve
Time spend or estimated to be spend on an issue cannot be set or seen from the issue boards. Furthermore the time spend cannot be set through commit messages, which are often used to close issues.
Intended users
Developers a.k.a. my-time-managers
Proposal
See and set estimated and spend time of an issue on the board directly. Furthermore allow commands /estimate and /spend in commit messages.
