Enable a PluginTemplateExtension subclass to register for multiple models

New functionality

Proposed functionality

A subclass of PluginTemplateExtension must currently register against a single model. For example:

from netbox.plugins import PluginTemplateExtension

class SiteCustomContent(PluginTemplateExtension):
    model = 'dcim.site'

This issue proposes adding an alternative models attribute to specify an iterable of models. For example:

from netbox.plugins import PluginTemplateExtension

class SiteCustomContent(PluginTemplateExtension):
    models = ['dcim.region', 'dcim.site', 'dcim.location']

The content introduced by this class will then be embedded on the relevant view for each of the listed models.

If models is defined, it will take precedence over model.

Use case

This obviates the need to create a redundant PluginTemplateExtension subclass for each core model.
