workflows: update workflow tasks

* Adds new filtering task for record categories, allowing to
  specify which categories to trigger an action in holding pen.

* Adds task results to objects in various tasks.

* Updates the sample harvesting workflow to use new bibclassify
  API.

* Several other updates and improvements to workflow tasks.

* Updates the category filtering task to allow regular expression
  syntax when defining which categories to halt, continue or stop
  the workflow.

* Adds new data type attribute to workflows, by Jan Aage Lavik.

* Updates the exception handling to better handle exceptions in
  workflows when running a workflow in a BibSched task.

* Improvements to category filter.

* Adds options for the foreach loop, we can now cache the
  list to go through it will then allow to five the choice
  to the user if he wants to priviledge CPU vs Memory,
  cache uses few CPU but a lot of memory and doesn't provide
  a dynamic list. Without the cache option, we recompute the
  list each time so we use much more CPU but we keep just
  the data needed so few memory, and the list is still
  refresh for each loop.

* Refactors use of extra_data in the engine.

* Changes the task foreach so that obj.data takes the value
  it has before the foreach. In the previous version we were
  keeping the last value of the foreach.

* Adds the function filtering_oai_pmh_identifier which
  allows you to filter the identifier. Mainly used to
  avoid processing already processed one.

* Adds features to  inspire_filter_category, now parameter
  can be passed throught the extra_data of the engine.

* Fixes some bugs with regex in inspire_filter_category

* Adds the function update_last_update which allows you to
  update the last_update time of a repository. It is
  important because the user can choose exactly where in
  the workflows he considers that a crash is not a problem
  for harvested documents.

* Adds the different features needed by the change from
  pickle to message pack in Celery, to the container for
  BibWorkflowObject exchange.

* Adds the inspire_filter_custom task which allows to
  filter record by examinating some field of its bibfield
  It is a generalization of inspire_filter_category.

* Reenables all the functions in full_doc_process
  workflow.

* Adds some control over the number of workflows generated
  it is to avoid the memory saturation or the messaging
  queue limit.

* Adds some protected name for workflows to avoid possible
  conflict with new task an new user data etc.

* Add some functions to control workflows states.

* Fixes PEP8 and clean code

* Deletes non-informative logs.

* Modifies the different workflows to take into account the
  previous modification made.
