Instructions for charm creation are out of date

[Corey Bryant]

The preferred way to install charm-tools is via snap (ie. snap install --classic charm-tools). Note this also installs the py3 version of charm-tools as py2 is no longer supported for charm-tools.

Also 'sudo ./setup.py install' in charm-templates-openstack installs a bunch of pip packages (including the py2 version of charm-tools) outside of a virtualenv so it would be nice to at least document that, as users will then have systems with apt and pip python packages installed which is not good and not supported from a distribution pov.

@Corey

So you mean we just need to replace the APT install with a snap install in the Charm Guide?

Actually there is more to this so I think we should include more under this bug. I'll update the description with my findings so far.

It seems that at least https://docs.openstack.org/charm-guide/latest/new-api-charm.html#prerequists is out of date so I'm going to update the bug description.
