systemd: encourage ceph-mgr to start in sync with ceph-mon

This change introduces the following behaviour:

- When ceph-mon starts, it will try to start ceph-mgr with the same
  instance id (Wants=), but will *not* fail to start if ceph-mgr
  doesn't start (i.e. the mon still works as it always did).
- ceph-mgr will start After= ceph-mon, and will stop and start when
  ceph-mon stops and starts, because it's PartOf= ceph-mon.

If you don't want ceph-mgr to run on the mons, you need to mask the
service, i.e. `systemctl mask ceph-mgr@INSTANCE`.  Hostnames are
typically instance names, so `systemctl mask ceph-mgr@$(hostname)`
should suffice if you wish to disable ceph-mgr on the mons.

ceph.spec.in: add ceph-mgr package

This adds ceph-mgr following the same pattern used for ceph-mon,
ceph-mds, ceph-osd.  I've removed the boost-python BuildRequire
for SUSE distros, because we don't ship that (the relevant bits
are already included in boost-devel).

NOTE: This gives an installable ceph-mgr, but not necessarily a
runnable ceph-mgr.  This is because ceph-mgr needs the following
python packages:

- CherryPy
- Django
- gevent
- python-dateutil
- djangorestframework

Not all of these are available as distro packages.  For example,
on openSUSE Tumbleweed, we don't have djangorestframework available
in the base distro, and our Django version is 1.9, which seems to
be incompatible with ceph-mgr.  I'm not sure of the situation on
other distros.

mgr: api_docs.py: Update for use outside Calamari

The ceph_state module is implemented in C++, and isn't available at
build time, which causes import failures when api_docs.py tries to
import calamari_rest in order to introspect it (MgrModule is eventually
imported, which in turn tries to import ceph_state, which fails unless
we stub it out).

Additional changes:

* Search calamari_rest.urls (not calamari_web)

calamari_web isn't available - it largely held static content in
Calamari, and in turn included calamari_rest.urls.  Here in ceph-mgr we
only have calamari_rest.

* note that --list-urls does nothing, apparently

* Pass actions to old as_view method

django-rest-framework 3.x raises TypeError if the actions argument isn't
passed to as_view().

* Use view().get_view_name() instead of metadata

Attempting to access view().metadata(None)['name'] results in
"AttributeError: 'super' object has no attribute 'metadata'".

* Use somewhat unfriendly field class names

django-rest-framework 3.x seems to have done away with type_label for
fields, so instead use the field's class name, which is somewhat
unfriendly, but arguably better than nothing.

* import global_instance to fix ImportError

This is necessary to avoid what seems to be weird import loops (if this
isn't present, we later get "ImportError: cannot import name
UserRequest" or similar).

* Make api_examples.json optional

This way we at least get bare docs with no examples, rather than no docs
at all.

* Explain how to generate API docs
