queue remove: add remove support for short revs(#7840)

[karajan1001]

fix: #7840

Now queue remove can not accept short rev as name.

1. We add support for short rev as name in queue remove.
2. Better output if no queue task found for name.
3. short rev on kill can only be work for rev with lens longer than 4

@karajan1001 latest changes look good, I'd still like to get rid of the string length check though (see latest review comments)
