Connection timeout due to conntrack limits

[Khaled El Mously]

Customers of GKE 1.25 and 1.26 are affected by the conntrack performance issue that causes random connection timeouts. The fix has been committed to to the upstream's net git repo and to prodkernel and needs to be backported to Ubuntu versions with kernel 5.15.

This issue was originally reported on GKE and verified by the GKE team. We do not have reproduction steps.

As it is a change from upstream and a simple constant change, and since it is has already been verified on GKE, I am verifying it on GCP by code inspection.
