Support test-kitchen's regex for platform names

[StephenKing]

Thanks for test-kitchen support!

I'm not sure if it is technically possible, but I would appreciate it, if the syntax for specifying platform names would be in line with the one of test-kitchen.

I can do

kitchen converge debian

while I have to specify exactly

chef-runner default-debian-76

Or would this wildcard-matching contrary to chef-runners approach, because c-r always only targets one platform, not multiple (as possible with t-k)?

Feel free to directly close it, if it makes no sense to you!

The current implementation is pretty dumb in that it only tries to parse .kitchen/<instance name>.yml. There's not a lot more magic to it.

What you're requesting is possible BUT:

• I think it would require parsing .kitchen.yml for all existing instance names and than applying Test Kitchen's wildcard logic. Alternatively, chef-runner could shell out to kitchen list REGEXP, but it's just so damn slow.
• chef-runner would either fail if the regexp would expand to more than one machine or -- if I added multi-machine support -- provision all matching machines similar to Test Kitchen.

Considering that I thought about adding multi-machine support some day, I might as well support Test Kitchen's regexp syntax. So I will keep that in mind. :)
