Group related panels into packages

[Radomir Dopieralski]

It's possible in Horizon to have the panels grouped into PanelGroups in the menu, but unfortunately that is not reflected in the filesystem structure of the panel source files. We found a way of grouping related panels together into packages by using dot notation, like this:

class DeploymentOverview(horizon.Panel):
    name = _("Overview")
    slug = "deployment.overview"

class Deployment(horizon.PanelGroup):
    slug = "deployment"
    name = _("Deployment")
    panels = (
        'deployment.overview',
        'deployment.controller',
        'deployment.compute',
        'deployment.object_storage',
        'deployment.block_storage',
    )

This works fine with panel autodiscovery and would be a perfect solution for this problem, if not for one detail -- the URL generated for such a panel looks like: /infrastructure/deployment.overview/

This can be easily fixed by a small change in how the URLs of the panels are generated.

    Fix URLs of panels grouped into packages

    If you group related panels into packages using the
    dot notation, the URLs generated for them will have
    the dot in them where you would rather expect a
    slash. This patch fixes it by replacing the dots in
    the panel slug with slashes when generating URLs for
    them.
