S(sWWait for mcpd to become available

        All configuration happens in mcpd so we need to wait that this is
        available before we go provisioning the system. I call this method
        at the first opportunity I have (during the DVD mounting call).
        This ensures that the rest of the provisioning does not need to wait
        for mcpd to be available unless it absolutely wants to.

        :return bool: Returns True upon success
        :raises OSUtilError: Raises exception if mcpd does not come up within
                             roughly 50 minutes (100 * 30 seconds)

S(s>Set the static hostname of the device

        Normally, tmsh is used to set the hostname for the system. For our
        purposes at this time though, I would hesitate to trust this function.

        Azure(Stack) uses the name that you provide in the Web UI or ARM (for
        example) as the value of the hostname argument to this method. The
        problem is that there is nowhere in the UI that specifies the
        restrictions and checks that tmsh has for the hostname.

        For example, if you set the name "bigip1" in the Web UI, Azure(Stack)
        considers that a perfectly valid name. When WAAgent gets around to
        running though, tmsh will reject that value because it is not a fully
        qualified domain name. The proper value should have been bigip.xxx.yyy

        WAAgent will not fail if this command fails, but the hostname will not
        be what the user set either. Currently we do not set the hostname when
        WAAgent starts up, so I am passing on setting it here too.

dS(s?Create user account using tmsh

        Our policy is to create two accounts when booting a BIG-IP instance.
        The first account is the one that the user specified when they did
        the instance creation. The second one is the admin account that is,
        or should be, built in to the system.

sChange a user's password with tmsh

        Since we are creating the user specified account and additionally
        changing the password of the built-in 'admin' account, both must
        be modified in this method.

        Note that the default method also checks for a "system level" of the
        user; based on the value of UID_MIN in /etc/login.defs. In our env,
        all user accounts have the UID 0. So we can't rely on this value.

dS(s.Find BIG-IP's CD/DVD device

        This device is almost certainly /dev/cdrom so I added the ? to this pattern.
        Note that this method will return upon the first device found, but in my
        tests with 12.1.1 it will also find /dev/sr0 on occasion. This is NOT the
        correct CD/DVD device though.

Return the interface name, and ip addr of the management interface.

        We need to add a struct_size check here because, curiously, our 64bit
        platform is identified by python in Azure(Stack) as 32 bit and without
        adjusting the struct_size, we can't get the information we need.

        I believe this may be caused by only python i686 being shipped with
        BIG-IP instead of python x86_64??
