test: Add Calico Inbound and Outbound policies to LKE nodes for E2E

[ykim-akamai]

📝 Description

A new script, lke_calico_rules_e2e.sh, has been added and is called in the E2E workflow file after the Run the integration test suite step in e2e-suite.yml

Key Points:

• kubectl and calicoctl binaries are required as pre-req which are downloed in the e2e worflow file
• The script retrieves all LKE clusters in the test account and applies Calico rules to the corresponding nodes. If no clusters exist, no action is taken. In most cases, clusters are cleaned and deleted properly after test execution
• Due to the delay in the availability of LKE cluster configurations and the provisioning times of node instances, it is challenging to apply Calico rules directly within the test framework. Therefore, the script is separated and executed independently in the workflow file

✔️ How to Test

PR has been checked out

1. Comment out remove_lke_clusters() line 64 in test_clusters.py
2. Run make MODULE="lke" testint
3. Run shell script cd scripts && ./lke_calico_rules_e2e.sh
4. Calico rule is applied to the cluster

Great work so far! Just a few tiny suggestions and this should be good to go 🎉

Works well on my end, nice work!

Tested using the following:

1. Create two LKE clusters:

 linode-cli lke cluster-create --region us-mia --k8s_version 1.29 --node_pools.type g6-standard-1 --node_pools.count 2 --label test-cluster-1

 linode-cli lke cluster-create --region us-mia --k8s_version 1.29 --node_pools.type g6-standard-1 --node_pools.count 2 --label test-cluster-2

3. Apply calico rules using provided script:

cd scripts
./lke_calico_rules_e2e.sh
