Open the possibility of using multiple deployment files

[gustavoborragan]

For cases in which the deployments file is very large and becomes unreadable, unmanageable, or where you want to segregate it for reasons of logical division, it would be good to open up the possibility of adding several files. One possibility would be that, in the case of more than one deployments.*.yaml file, the action would detect this case and merge them.

@gustavoborragan could you provide an example of the use case?
