upgrade script for secure Fuel Master services

[Matthew Mosesohn]

Here the dict that we need to add to astute.yaml when upgrading from 5.0 to 5.1:
"astute/user": "naily",
"astute/password": "naily",
"cobbler/user": "cobbler",
"cobbler/password": "cobbler",
"mcollective/user": "mcollective",
"mcollective/password": "marionette",
"postgres/keystone_dbname": "keystone",
"postgres/keystone_user": "keystone",
"postgres/keystone_password": "keystone",
"postgres/nailgun_dbname": "nailgun",
"postgres/nailgun_user": "nailgun",
"postgres/nailgun_password": "nailgun",
"postgres/ostf_dbname": "ostf",
"postgres/ostf_user": "ostf",
"postgres/ostf_password": "ostf",

Note that / represents a subdict and is not a literal slash in the yaml key.

    Upgrades, add credentials to astute.yaml

    Feature `access control on master node`
    was introduced in 5.1 release.
    In this feature fuelmenu generates credenitals
    and saves them in /etc/astute.yaml file.
    Before upgrade for this featuer we need to
    add default credentials to the file for 5.0.X
    versions.
