No cf api for checking login state (#1785)
* Dont work upon a global command.Command instance inside cloudfoundry package

o Up to now we work on a private and shared instance of command.Command inside
  the cloudfounrdy package. We need to be able either configure this instance
  (environment variables) according to the use case. One option is to hand over
  an already configured instance which is used elsewhere. This is what we do with
  this commit.

o With this commit we remove the instance which is shared within the cloudfounrdy
  package and to provide an instance with a receiver which gets handed over to the
  functions. Hence we are thread save: parallel invoctation of e.g. Login will not
  affect each other.
