Implement a copy function for collections

[hechth]

It would be cool if collections could be copied the same way as it is currently possible for data objects using a single function call to the respective manager.

recursive calls are currently client-driven...

implementing server-side recursion might depend on something like... https://github.com/irods/irods/issues/7213

icp handles this via cpUtil.cpp in irods/irods, which is part of irods-dev(el), which is available to the C++ client iCommands.

Currently, other languages have to handle this logic themselves... which is... not what we want for the long term. Hence a server-side solution would be nice/good.

Whether or not it was ever meant to be used, we have had this thing sitting around for quite a long time... https://github.com/irods/irods/blob/aff93a3fbe417c8ec2e9d834b5eb2d6b2ae31083/plugins/experimental/src/copy.cpp#L40

[trel]

but... is that available for use by a call from Python?

[alanking]

It's an API plugin, so... yes?

[trel]

Well, right, that's so smart.

Hmm... an "experimental" plugin. Maybe not.

Easily done in pure python too. Even easier if we use pyfilesystem2's fs.walk()
