    Change collect to use /etc/platform/openrc

    The collect tool is failing to source the openrc file
    needed to execute system commands to get inventory.

    The openrc file has been moved to /etc/platform but
    collect expects it to be in /etc/nova.

    This update changes collect to source openrc from
    /etc/platform in collect_utils and avoids needless
    sourcing of that same file multiple times from the
    other collect scripts. All collect scripts source
    collect_utils.

    The update also removes reference to the also recently
    removed keyring which is also breaking collect in the
    very same way.

    Test Plan:
    Run collect on individual hosts
    Run collect all
