Added Jobs() container (similar to Views())
Fixed improper requester
Keep the same scheme (protocol) as was used in Jenkins constructor in all requests

Some Jenkins instances are configured to allow reading the data over HTTP scheme, while for manipulating with
data (e.g. create or delete job) HTTPS scheme is required. Allow user to specify preferred URL scheme (by
specifying Jenkins URL) and use this scheme also manipulations with jobs.

This was introduced in 4f29f6742410736016b568002d8569f19d786841 (version 0.1.13) but lost again in

Add kerberos authentication requester using requests_kerberos
Merge pull request #157 from pkocandr/unstable-krbrequester

Add kerberos authentication requester using requests_kerberos
Build.get_downstream methods

These methods do not return the proper data.  Fixing them and adding a
unit test for them but i'm not familar with magicmock so its having an
issue.

Temporarily disable a test.
Raise NoBuildData when latestBuild etc. not even set

The Folders plugin uses jobs as a container for folders.
However, a lot of standard job keys, such as lastBuild et al.
are not even present (unlike a never run job where they are
present but set to None)

Since a value of None for latestBuild causes a NoBuildData
exception, the same exception should be fine when not present.
Try to be consistent about what type is returned

still broken
fix up some imports
