Defautl GUEST_MTU=1500 on Virtual Networks prevents correct deployments in Equinix BareMetal

[apiconc]

Description
Default MTU=1500 prevents OneKE deployments in Equinix Baremetal to deploy correctly. The correct MTU size should be 1450.

To Reproduce

1. Provision an Edge Cluster in Equinix Baremetal
2. Deploy a kubernetes cluster using OneKE on the Equinix Baremetal
3. Deployment fails with workers/masters never joining the cluster and failures with oneflow service
4. Change GUEST_MTU=1450 on public/private network
5. OneKE deployment completes successfully

Expected behavior
OneKE appliance should deploy correctly in Equinix Baremetal instances
