Description of problem:

With the current Agent based installer we need to have a option to specify
some more details while we use DHCP. Current configs aligns to nmstate which
takes the agent config to consideration and likely following will fail,
--------------------

apiVersion: v1alpha1
kind: AgentConfig
metadata:
  name: ocp4
rendezvousIP: 10.47.xx.xx
hosts:
  - hostname: master-0.ocp4.xyz.com
    role: master
    interfaces:
      - name: eno49
        macAddress: b8:83:03:81:0d:70
      - name: eno50
        macAddress: b8:83:03:81:0d:71
    rootDeviceHints:
      deviceName: /dev/sda
    networkConfig:
      interfaces:
        - name: bond0
          type: bond
          state: up
          mtu: 9000
          mac-address: b8:83:03:81:0d:70
          ipv4:
            enabled: true
            dhcp: true
          link-aggregation:
            mode: 802.3ad
            options:
              miimon: "150"
            port:
             - eno49
             - eno50
      dns-resolver:
        config:
          server:
            - 10.47.xx.xx
      routes:
        config:
          - destination: 0.0.0.0/0
            next-hop-address: 10.47.108.1
            next-hop-interface: bond0
            table-id: 254

----------------

Here, the requirement is to have the DHCP offering along with privilege to get
the bonding configured which isn't possible with current agent based
installer. If we try something like above it will fail as per the
"error-output-for-the-create-image-command.txt" file attached here.

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

4.12

How reproducible:

- Create an agent config as per above to have bonding created where the IP addresses would be DHCP reservations.
- Run the installer

Steps to Reproduce:

1. Create agent config to have DHCP with Bond config
2. Run the command to create ISO
3.

Actual results:

- Results in to errors and from documentation we don't see any options to have
this kind of setup.

Expected results:

- Shall allow DHCP bonding with declaration of DHCP reservations with specifying routes with nmstate.
