Feature Request: Allow for mgmt IP to be static setting

[thomsonjames]

Currently, the Openstack-network.sh has settings for the tmm interfaces and you can set dhcp to false. We'd like to request a feature be added whereby the mgmt interface could have the same options along with the settings for IP address and netmask. command-wise, the global setting for dhcp_mgmt would need to be set to disabled and then a static IP defined.

Please let me know if you need any more information or if the setting exists and I just can't find it.

My customer does not use DHCP on the mgmt interface and would also benefit from this request.

Lines can be added in the os-network.sh script in order for it to find the mgmt IP addresses and other parameters such as default GW and eth0 MTU from the json user-data file in the config-drive and use those values to configure mgmt where DHCP is not being used on mgmt interface.

The json file portion for network parameteres}, "network": { "mgmt_routes": { "mtu": "mgmt_mtu", "gateway": "mgmt_gateway" }, "interfaces": { "mgmt": { "dhcp": "false", "address": "mgmt_address", "netmask": "mgmt_netmask" }

When VM is instantiated this is how user-data looks with values populated. Active:Standalone] ~ # mount /dev/hdd /mnt

cat /mnt/openstack/latest/user_data },

    "network": {
        "mgmt_routes": {
               "mtu": "1400",
               "gateway": "11.0.0.1"
            },
         "interfaces": {
