Description of problem:

Controller supports Network Map destination type: ignored, user can set "destination type: ignored" in Network Map YAML file, the data is inconsistent between YAML file and UI, need to add the support on UI pages:
a. Create migration plan -> Network mappings page
b. Plan -> Plan Details -> Mappings: Network map page
c. NetworkMaps -> NetworkMap Details -> Map page

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

MTV 2.8.1-5(IIB: 953510) with CNV 4.17.8

How reproducible:

Always

Steps to Reproduce:

1) Create VM: mtv-func-win2022 on vSphere 7 with network settings as below:

mtv-func-win2022: 1 interface with DHCP settings

2) Create warm migration plan: warm-win2022, to migrate VM: mtv-function-win2022 to ocp cluster

3) There is no item E.g: "Ignore this network", thus select the Target network: Pod Networking

4) Edit the Network Map: v7-us-hz8v8 YAML file, map the "VM Network" to type: ignored

5)  In Plan -> Plan Details -> Mappings: Network map page, "VM network" map to "Not available", no item E.g: "Ignore this network"

6) Check NetworkMaps -> NetworkMap Details -> Map page: the "VM Network" is map to Pod, and no item E.g. "Ignore this network"

Actual results:

In step 3,5,6: the data is inconsistent between Network Map YAML file and UI

Expected results:

In step 3,5,6: the data is consistent between Network Map YAML file and UI
