Adding pod template support for field: AutomountServiceAccountToken

Release Note

NONE

[hernanDatgDev]

Hi, I'm not sure what value should actually be added for the "protobuf" string in pkg/apis/camel/v1/integration_types.go. The value I gave was protobuf:"varint,8,opt,name=automountServiceAccountToken" taking inspiration from other boolean values however the 8 is just a guess. What's an appropriate value to add when introducing new fields?

You can follow the k8s api podspec and set 21

@claudio4j Thanks I found the right values. Also I noticed in pkg/apis/camel/v1/integration_types.go it has some outdated make goal. To get the right functionality I ran make generate instead. Would it be appropriate to update this comment as well?

Run "make generate-deepcopy" to regenerate code after modifying this file

Yes, thanks.

Can you squash the commits once you have it ready for review ?

I added the test to ensure that the field is set properly on the deployment. I also relayed with my security team and it we only need this field so that we can set it to false which does not interfere with Knative. It is only when this field is explicitly set to True that Knative interferes through validation. So for my team and this field specifically this PR would be enough. There are other fields that we'd like set however those do have issues with Knative so I'm working on getting conversations started with the Knative teams.

I'm not familiar with knative, but this behavior seems to be a corner case of knative. As this is documenteded on knative, I'm ok with the addition of this field.
