[k8s-R5.0.1]: k8s cluster name should be appended over the contrail firewall policy

Nested k8s provisioning
Multi cluster setup

The contrail firewall policy created on creating k8s network policy should have cluster name appended over it to avoid conflicts.

Currently, the non default firewall policies created in contrail are having following name:
<namespace_name>-<policy_name>.
If we create same namespace and use same policy name across 2 different clusters, the latest setting override the previous one.
The same FW Policy is applied to both the APS groups of 2 different clusters and affect traffic of one of them.

Attached is the snapshot showing FW policy "test-test-Network-Policy" which is attached to APS of both k8s cluster named k8scluster2, k8scluster1.
Rules under the policy will be inferred from the recent update from wither of the cluster.

Prepend cluster name to Firewall Policies.

This commit prepends cluster name to Contrail Fw policy object.
This is crucial in nested multi-cluster enviroment where netpol with
same name can exist in more than one cluster. Hence the need to qualify
the policy with cluster name so as to avoid collision.
