Support overlapping repos and a flat workspace scheme

This adds the concept of a 'scheme' to the merger.  Up to this point,
the merger has used the 'golang' scheme in all cases.  However it is
possible with Gerrit to create a set of git repositories which collide
with each other using that scheme:

  root/example.com/component
  root/example.com/component/subcomponent

The users which brought this to our attention intend to use their repos
in a flat layout, like:

  root/component
  root/subcomponent

To resolve this we need to do two things: avoid collisions in all cases
in the internal git repo caches of the mergers and executors, and give
users options to resolve collisions in workspace checkouts.

In this change, mergers are updated to support three schemes:

  * golang (the current behavior)
  * flat (new behavior described above)
  * unique

The unique scheme is not intended to be user-visible.  It produces a
truly unique and non-conflicting name by using urllib.quote_plus.  It
sacrifices legibility in order to obtain uniqueness.

The mergers and executors are updated to use the unique scheme in their
internal repo caches.

A new job attribute, 'workspace-scheme' is added to allow the user to
select between 'golang' and 'flat' when Zuul prepares the repos for
checkout.

There is one more kind of repo that Zuul prepares: the playbook repo.
Each project that supplies a playbook to a job gets a copy of its repo
checked out into a dedicated directory (with no sibling repos).  In that
case there is no risk of collision, and so we retain the current behavior
of using the golang scheme for these checkouts.  This allows the playbook
paths to continue to be self-explanatory.  For example:

  trusted/project_0/example.com/org/project/playbooks/run.yaml

Documentation and a release note are added as well.

@ -866,3 +866,36 @@ Here is an example of two job definitions:
This means that changes to jobs with file matchers will be
self-testing without requiring that the file matchers include
the Zuul configuration file defining the job.
.. attr:: workspace-scheme
:default: golang
The scheme to use when placing git repositories in the
workspace.
.. value:: golang
This writes the repository into a directory based on the
canonical hostname and the full name of the repository. For
example::
src/example.com/organization/project
This is the default and, despite the name, is suitable and
recommended for any language.
.. value:: flat
This writes the repository into a directory based only on the
last component of the name. For example::
src/project
In some cases the ``golang`` scheme can produce collisions
(conisder the projects `component` and
`component/subcomponent`). In this case it may be preferable
to use the ``flat`` scheme (which would produce repositories
at `component` and `subcomponent`).
Note, however, that this scheme may produce collisions with
`component` and `component/component`.

---
features:
- |
Jobs may now specify an alternate scheme to use when preparing
repositories in the workspace. The default remains the same
golang-style, but an alternate scheme called `flat` is now
available. See :attr:`job.workspace-scheme` for more details.
upgrade:
- |
The internal git repo caches maintained by the mergers and
executors now use a new naming scheme in order to avoid
collisions. When existing executors and mergers are restarted,
they will remove their git repo caches and re-clone repos using
the new scheme. Jobs may be slow to start until the caches are
warmed again.
