Support consul exec with a lock/semaphor

[sethvargo]

The consul lock command is great (and can be used in tandem with consul exec), but it would be great if consul exec accepted a -n parameter and handled all the locking automatically:

$ consul exec -n=3 -service='webapp' ./deploy.sh

This would be really great for rolling deploys or even Kernel upgrades:

$ consul exec -n=10 sudo reboot now

I like this! Seems like a nice UI improvement, and it would take care of creating a temporary lock name / guid kind of thing for each invocation.

[armon]

Agreed!

I would like this as well for the same reasons as sethvargo.
Are there any plans to include this in an upcoming release?

Closing due to inactivity. I'm trying to get the list of issues I've submitted under control, and it doesn't look like there's interest in building this functionality at this time.
