BulkImport naming inconsistency

[wkoot]

Proposed Changes

Either rename views.generic.BulkImportView to views.generic.ImportView, or alter the urlpatterns to name='*_bulk_import'.
For backwards compatability, the BulkView could be an alias or urlpattern name='*_import' could be supported until a next major release.

I believe that renaming the urlpattern is better, since an import action could add only a single object (i.e. with a plugin connecting to an external service).
In this case, the NetBoxModelImportForm should probably also be renamed to NetBoxModelBulkImportForm.

Justification

The current implementation is inconsistent; the other bulk urlpatterns are named _bulk_add, _bulk_edit, _bulk_rename and _bulk_delete.
See for instance netbox/dcim/urls.py and netbox/ipam/urls.py.
