Fixed few UI tests
Few updates for the manifests modules.

Removes the `install_cert_on_server` function as it's logic is now
moved to automation_tools github repo.

Updated Sphinx Directives for all the functions.

Now the `clone` function uses a default `key_file` and `old_path` values
to fetch manifest from the robottelo.properties file.

Some multiline doc fixes and the usage of os.path.join

Adds multiline docstrings fixes for the manifest module functions.

Also replace the usage of '+' with os.path.join function.

[Do Not Merge]Few updates for the manifests modules.
Flesh out ComputeResource entity, test it.

When creating a new "compute resource" entity, a variable set of values must be
provided to the Foreman server. The exact set of values depends on the specified
provider. (e.g. EC2, Rackspace, etc.) Flesh out the ComputeResource entity with
logic necessary for handling this variability in requirements.

Add some API tests for the ComputeResource entity. It is currently *only*
possible to create a libvirt compute resource. All other tests fail for a
variety of reasons. For example:

* Creating a compute resource with a provider of 'Rackspace' causes Foreman to
  throw an HTTP 500 with the message "undefined method `upcase' for
  nil:NilClass".
* Creating a compute resource with a provider of 'GCE' fails because Foreman
  needs more data. However, the types of data needed are not discussed in the
  API docs.
* Creating a compute resource with several other providers causes Foreman to
  return the following error: "getaddrinfo: Name or service not known".
