add match to envvar

use-case: Different teams need to check whether the format of environment variables is uniform. It is also necessary to check that the environment variable conforms to a regular expression.

eg: AppDynamics app name: ^WEALTH-(\w{2})-(\w{4})-[\w_]+-(DEV|UAT|PROD)$

I understand that. But can't this be achieved under the status quo? How does this new parameter help?

[siperman]

Because my test reverses the entire regular, it does not take effect. Remember that the reason for the search is that the golang regular library does not support inversion.

Ohh I see. Yeah, we currently support this by allowing people to add a ! at the beginning, to signify negation. This is probably not as well-documented as it should be.

@siperman You should be able to set the value in the check to !^WEALTH-(\w{2})-(\w{4})-[\w_]+-(DEV|UAT|PROD)$, and then I think it will do what you want?

@siperman What's the status of this?
