In an OCP Cluster, openshift-dns namespace has dns-default
service and this is controlled by its operator.
When Globalnet is deployed on OCP, it was seen that globalip
annotation added to it is periodically getting deleted by the
operator, so Globalnet tries to re-add the annotation and this
goes on forever. This will cause Globalnet to consume CPU
unnecessarily and could affect user-experience with Submariner
Globalnet. We have plans to enhance Globalnet to improve its
scalability, but until then we can exclude annotating services
in openshift-dns namespace.

In an OCP Cluster, openshift-monitoring namespace has couple of
services and these are controlled by their respective operators.
When Globalnet is deployed on OCP, it was seen that globalip
annotation added to such services are periodically getting
deleted by the operators, so Globalnet tries to re-add the
annotation and this goes on forever. This will cause Globalnet
to consume CPU unnecessarily and could affect user-experience
with Submariner Globalnet. We have plans to enhance Globalnet

annotating services in openshift-monitoring namespace.

In one of the earlier PRs, we modified the terminationGracePeriodSeconds
to 10 secs. However, its seen that this is causing more CI failures
during e2e redundancy tests. Ideally, once the Pods are terminated,
it should cleanup itself ASAP but it is seen that SM Pods are sometimes
taking time to exit and during this Period since there is no active SM
Pod running, this is triggering some failures.
Until we figure out the exact reason why the Pods are taking time for
cleanup, this PR reduces the terminationGracePeriodSeconds.

In K8s the default termination grace period for a Pod is 30
secs. However, for Submariner Pods, we were configuring this as
0 secs, because of which, cleanup was not happening in a
consistent manner and we are seeing failures in CI jobs.
This PR modifies the terminationGracePeriodSeconds to 10 secs.
Along with this change, it also uses the proper namespace of
submariner in the excluded namespaces.

Added a chart for the globalnet controller which uses the global CIDR.
Also added the global CIDR to the submariner engine pod env so it can
utilize it.
The controller will only be deployed if the CIDR is specified.
