os_blazar role is outdated, does not work

[Alexey 'Fenuks' Rusetsky]

os_blazar role seems to be outdated and it does not work with Keystone correctly.
[keystone_authtoken] variables are old and endpoint needed a v1 at the end.

Also, os_nova needs some modifications to work with blazar.

Attached are patches that worked for me.

    Improve Blazar integration with Nova

    As of today we do not have any means of Blazar integration with Nova,
    while we do provide roles for Blazar installation for a while now. This
    patch aims to bring in more native integration and remove necessity
    of overrides for such deployment.
