  [#3606] Allow plugins to react to forks of the CKAN process

This commit introduces the IForkObserver interface which allows
extensions to react to forks of the CKAN processes using the interface's
before_fork and after_fork methods.

This mechanism is then used to prevent a sharing of the DataStore's
SQLAlchemy engines between processes.

  [#3606] Remove IForkObserver.after_fork

After fork notifications are currently not required to fix the issue at
hand but at a lot of implementation complexity. They are therefore
removed until need arises.

  [#3606] Use duck-typing to call before_fork in the PostgreSQL backend

This avoids unnecessarily inflation of the DatastoreBackend interface.
If it turns out that the IForkOberserver events (or events from other
interfaces) are often of interest in DataStorebackend implementations
then a good approach would be to make them real CKAN plugins so that
they can implement the desired interfaces themselves.

  [#3606] Add test case for Datastore backend jobs problem

This test case captures the problem described in issue #3606: if
multiple background jobs access the Datastore then the first of them
succeeds while the following ones fail with various exceptions related
to database connections being closed unexpectedly.
