'copy' collector should work with directories

[laverya]

Currently the copy collector calls cat within the container, which doesn't work with directories - only individual files. This is rather suboptimal.

Hi @laverya @markpundsack, I found a solution that would allow copy collector to get all the files in a folder and its sub-folders. But, should it have a limit? Should we not copy some specific type of file?

[markpundsack]

I don’t have any strong opinions on this. Being able to specify a pattern sounds useful too, but I do imagine some people will need to simply copy a entire directory, knowing that it only contains the kind of files they are looking for.

@markpundsack Sound good! I've created the PR with the modifications! Let me know if there is something you would like to change!

@manavellamnimble @divolgin Did the changes include documentation?

[manavellamnimble]

@markpundsack @divolgin I was about to ask about this in the chat! If you want I can ask about it on slack, so we are all in the same page
