Speed up the certification for new openshift versions ( at least for LTS )

[jsalatiel]

Is your feature request related to a problem? Please describe.

Currently installing antrea as primary CNI on the latest 2 openshift versions is unsupported. According to redhat , antrea is only certified for openshift 4.11.x and 4.12.x. That excludes antrea as CNI for any user wanting to install the recommended openshift version ( 4.14.x now )

Describe the solution you'd like

Taking a look at other certified CNIs I can see that both Calico and Cillium already support 4.13 and 4.14. They also fullfil the capability level of seamless upgrades.

Calico:

Cilium:

It would be nice if antrea could keep up to date with the new openshift versions, at least for their LTS version.

Describe alternatives you've considered

For 4.14 the only alternative is calico or cilium

Additional context

btw, what exactly means that "seamless upgrade" capability level?
Can't antrea fullfil that too ?
