Skip known-failing test

When one fetches information about a GPG key, the following fields are returned:

* content
* created_at
* id
* name
* organization
* permissions
* products
* repositories
* updated_at

Note that 'organization' is returned, not 'organization_id'. This is bad
behaviour, and GPG keys therefore also suffer from the problem described in
bugzilla bug 1122267.

Add a ForemanTask entity

Additinally, override method `ForemanTask.path` and add some tests for this
custom behaviour.
Partially flesh out entity ForemanTask

Add the following methods:

1. ForemanTask.path
2. ForemanTask.get_result_or_timeout

The former should be fully implemented, but the latter has only pseudocode.
Neither is tested.
Implemented code for `entities.Tasks.poll`.

Implemented the code that allows you to poll the status for an aysnc
task (such as a repository synchronization for example). The method
'polls' for the status of the task and returns it once it is no longer
running (`'pending'` == False) or it will raise an exception if we go
beyond the 'timeout'.
Silencing Travis due to E501.
Handling several comments and suggestions.
