[ytt] Support an array in config_yaml attribute

[braunsonm]

Describe the problem/challenge you have
Since on the command line with ytt you can pass in multiple config files, you should be able to use this property to pass in an array of YAML configs. This is a common usecase where the YAML is retrieved from another terraform data source and read off as a property. For instance we grab some YAML from Vault and feed it into our ytt data source.

Describe the solution you'd like
A config_yaml property that supports an array of YAML source which is added to the ytt overlay command.

Anything else you would like to add:
You can get around this issue by using a join config_yaml = join("\n\n", [yaml1, yaml2]) for now.

Bump

[cppforlife]

challenge here is that there is only one stdin (that's where config_yaml is piped into). im not sure how we could do this securely without introducing new feature to ytt to support getting content from other file descriptors.
