As a common approach most projects used now and Oslo preferred, this
change enabled sample configuration file generation mechanism for
each Glance services.
This change, as an enhancement, allows generating separated sample
configuration files for each Glance major services, e.g.:
etc/glance-api.conf.sample
etc/glance-cache.conf.sample
etc/glance-manage.conf.sample
etc/glance-registry.conf.sample
etc/glance-scrubber.conf.sample
It is different than I94d486d6686815c45705a7a9b00fb26062e1eb63
which only supports generating an unified sample configuration
file to including all Glance available options.
This mechanism not only can help auditing by packager, milestone
maintainer or developer as a function (testenv) of tox, but also
those separated configuration files could make deployment be easy.
And it helps keeping sample configuration files be update with
code change.
The change added "genconfigs" function as a tox testenv (-egenconfigs),
and it dependes on oslo-config-generator function of oslo.config.
The change doesn't introduce those sample files Glance repo, so
next step is to investigate if we can generate them in gate
automatically when a change was merged.
