[dashboard] Instead of specific breadcrumbs need to use horizon ones

[Ekaterina Chernova]

Now horizon has opportunity to support bread crumbs in the django templates. So murano-specific crumbs can be replaced with horizon:

{% breadcrumb_nav %}

 https://review.openstack.org/271383 adds this functinality, but we still have Applications -> Application Details use custom title/breadcrumbs. Should be relatively easy to fix.

    Use horizon breadcrumbs style instead of custom

    Murano has its own breadcrumbs style before
    it was introduced in horizon.
    So now it's better to be consistent with
    horizon and use one style.
