Description of problem:
Opening a Spice console in rhevm-shell might fail due to wrong display.port parsing

Version-Release number of selected component (if applicable):
3.5

How reproducible:
always

Steps to Reproduce:
1. Start rhevm-shell and connect to rhevm with "-d" switch
2. run "console <VM>" command on a VM with Spice Console

Actual results:
The console does not open. Debug output shows:
"spicec: invalid port value None"
Without the "-d" switch simply nothing is displayed.

Expected results:
The spicec should start and display the console

Additional info:
A typical display portion of spice-display looks as follows:
        <display>
            <type>spice</type>
            <address>10.32.96.26</address>
            <secure_port>5950</secure_port>
            <monitors>1</monitors>
            <single_qxl_pci>true</single_qxl_pci>
            <allow_override>true</allow_override>
            <smartcard_enabled>false</smartcard_enabled>
            <file_transfer_enabled>true</file_transfer_enabled>
            <copy_paste_enabled>true</copy_paste_enabled>
        </display>

As there is no port given, the port is then saved as "None" in the vm.display.port field.

As an easy workaround the console.py can be changed as follows:
