Add support for IngressClass objects

[levikobi]

What would you like to be added:
Add support for reading and taking into account IngressClass objects.

Why this is needed:
If users do not specify ingressClassName, we need to understand the default IngressClass that should be used for the conversion.

I have created a PR for the same. Kindly review it.

[levikobi]

I just now noticed that @akagami-harsh asked to work on this issue first.
@akagami-harsh are you still interested in working on it?

[akagami-harsh]

@levikobi yes i am interested. i was busy with other things, but now i am free

[akagami-harsh]

Since there's already an open PR for this issue, should I create a new one?

[LiorLieberman]

Hi @akagami-harsh, no.
There is already a PR @Varun1300211 opened.

Please check out other issues like #81 if you are still up for contributing. We would love to have you.

@Varun1300211 While we appreciate you quickly made a PR and sent for review, next time, please kindly try to confirm with the current assignee if he is working on it before proceeding with a PR

[Varun1300211]

Apologies @akagami-harsh, I am still very new to the open source. Never seen you were already assigned to it before. Hope you understand.

Sure @LiorLieberman will keep it in mind from the next time onwards.

[akagami-harsh]

No worries at all, @Varun1300211! It happens, and I appreciate you being open to the feedback. Thanks for letting me know, @LiorLieberman . I'll take a look at issue #81.

@levikobi @LiorLieberman
If neither the ingressClassName field nor the kubernetes.io/ingress.class annotation is set on the Ingress, the tool skips processing that Ingress, resulting in no Gateway API resources?

[levikobi]

@levikobi @LiorLieberman If neither the ingressClassName field nor the kubernetes.io/ingress.class annotation is set on the Ingress, the tool skips processing that Ingress, resulting in no Gateway API resources?

At the time I opened this issue this was correct @VasuDevrani, I think this still holds true though.
The purpose of this issue is to add support for reading the ingressClasses, one of them should be the default. Then we will be able to convert ingresses without the field or annotation being specified

[mlavacca]

Hi @VasuDevrani, any news on this issue? If you need some help, please let us know :)

[TusharMohapatra07]
