reorganize doc dir

[laszewsk]

isue: the doc dir contains not only docs

solution: the doc dir should only contain the documentation. The generaion of reports is not documentation, but reports it must be moved in a different directory. The doc dir should just like all other cloudmesh doc dirs only contain the sphinx documentation.

The report sphinx naturaly needs to be separated from it.
