It maps the name of the config values that we use in our templates to
the name of the key in the snap config. This allows us to stick a
bunch of stuff in the questions namespace in the snap config, and to
use dashes, with minimal changes to our templates.
Drop Python 2 support, to fix tests.

We present these as seperate invocations of the script, rather than
automatically running them one after the other. This allows us to run
the setup script once for multiple daemons, then run launch steps
individually for the daemons.

This allows us to access values from the snap config in our templates,
just like we access the snap environment variables.

Add automatic addition of REQUESTS_CA_BUNDLE to the execution
environment if $SNAP_COMMON/etc/ssl/certs/ca-certificates.crt
is detected, allowing the certs from the core snap to be
overridden on a per snap basis.
This supports use of privately signed certificates in snap
based deployments.

Drop code that is no longer used or no longer required since the move
back to strictly confined snaps.
* Everything is run as root in strict snaps so there's no need
to drop privileges, no need to chown dirs/templates to anything
but root, and the default dir/file modes should suffice.
* copyfiles: we wanted to move away from this and finally did, so
so it's no longer used.
* rchown and rchmod: these are no longer used.
chmod is still used by nova-hypervisor, so let's keep it. I'm not
sure that we still need chown, but I've left that in case we happen
to.

The config override patch was a bit too aggressive in not allowing
multiple OpenStack config files/dirs to be specified. Some projects
need to specify more than one, so this re-enables the ability to
specify multiple OpenStack config files/dirs.
Additionally this makes the override of OpenStack config files more
flexible in that individual files can be overridden while others are
not.

Enables the ability for default config files to be overriden for
each entry point type (simple, uwsgi, and nginx).
Additionally, align unit tests with keystone's snap-openstack.yaml,
as features tend to land in the keystone snap first.

Refactor the template rending code into a static function.
Ensure that templates for the entry point are rendered during
execute, not the global templates.

As snaps only write out to snap specific locations, create locks
scoped to the individual snap, not globally for all snaps.
Change-Id: Ife03fb66eb97b89040495ffa51e867adca10a3a1
Targets for copyfiles and template directives should be considered
as owned by the snap, and as a result should always be executed,
irrespective of whether the target file exists or not.
This ensures that any use of {{ snap }} is current, and that changes
to templates in the snap are reflected on refresh.
Execute copyfiles prior to template rendering to ensure templated
files overwrite any files copied as a copyfiles target.

Specifying hard-coded config files via the uwsgi pyargv option
caused failures when a file didn't exist.
This patch enables dynamic creation of the pyargv option. This
value is pushed onto the context for templated file generation
which is now supported as a subelement of an entry point as
well as a top level global option.

Add support for running commands, defined by a snap, as a specific
user/group.
Additionally, file permissions and ownership of setup files can
be adjusted to limit access from other users.

By dropping the install setup key, snaps will decide for themselves
the full path where setup dirs, templates, and copyfiles are created.
Change-Id: I5347186cc586b54dfb11bf1884a0d804d5c1303f
Common utility functions that were defined in base.py are moved to their
own Utils class. Additionally this patch adds some checks to ensure keys
exist in setup() before attempting to access them.
Change-Id: Ib940eefce140e3552f41ff0e32123ae90fe81fe4
Add support for an install setup key that is set in snap-openstack.yaml
and defines whether the snap should be installed as a 'classic' or
'strict' snap. This determines the root directory where setup dirs,
templates, and copyfiles are created. If install is set to classic
the root directory will be / and if install is set to strict the root
directory will be $SNAP_COMMON.
Additionally the symlinks setup key is dropped. Classic snaps will
install files into / as defined by the install key.
Change-Id: I6750957654e75169108e6e866ab0d43e588cbd12
The code in OpenStackSnap.setup() creates users, files,
directories, symlinks, etc. Locking support is added to ensure
that setup() code is only executed by a single process at a time.

Missing configuration files are a 'normal' thing to expect, so
don't need to be logged as warning messages.
