When there is no LogBook nor backend in ZookeeperJob or something is wrong with book data, we now return None from `book` property instead of new (fake) LogBook. Having two (or more) logbooks with same uuid but different data is too confusing and makes root cause of the problem (backend or jobboard misconfiguration) less obvious. This change also adds `book_name` and `book_uuid` properties to Job abstract class to provide a way to access book data even if book itself cannot be fetched.

Testing and requirements
Requirements
Because TaskFlow has many optional (pluggable) parts like persistence backends and engines, we decided to split our requirements into two parts:
- things that are absolutely required by TaskFlow (you can't use
TaskFlow without them) are put to
requirements.txt; - things that are required by some optional part of TaskFlow (you
can use TaskFlow without them) are put to
optional-requirements.txt; if you want to use the feature in question, you should add that requirements to your project or environment; - as usual, things that required only for running tests are put
to
test-requirements.txt.
Tox.ini
Our tox.ini describes several test environments that allow to test TaskFlow with different python versions and sets of requirements installed.
To generate tox.ini, use the toxgen.py script by first installing
toxgen and then provide that script
as input the tox-tmpl.ini file to generate the final tox.ini file.
For example:
$ toxgen.py -i tox-tmpl.ini -o tox.ini
