feat: Added Integration Test for NodeCreateTransaction and FQDN support

[gsstoykov]

Description:
This PR serves as a POC for using NodeCreateTransaction. Adds the capability to create Networks via Endpoints containing domain names instead of IPv4 addresses.

Related issue(s):

Fixes #782 #732

Notes for reviewer:
Can be merged even if POC as it adds an Integration test. CI will fail against local-node so the test will be disabled(It needs Solo configured in our CI).

Checklist

• Documented (Code comments, README, etc.)
• Tested (unit, integration, etc.)

export SOLO_CLUSTER_NAME=solo-e2e
export SOLO_NAMESPACE=solo-e2e
export SOLO_CLUSTER_SETUP_NAMESPACE=fullstack-setup
kind delete cluster -n "${SOLO_CLUSTER_NAME}"
kind create cluster -n "${SOLO_CLUSTER_NAME}"

// Could create n nodes if listed like node1,node2... I strongly recommend 
// creating at most 1-2 nodes
npm run solo -- init --namespace "${SOLO_NAMESPACE}" -i node1 -s "${SOLO_CLUSTER_SETUP_NAMESPACE}"
npm run solo -- node keys --gossip-keys --tls-keys
npm run solo -- cluster setup
npm run solo -- network deploy --pvcs true
npm run solo -- node setup
npm run solo -- node start

// forwards the port which the SDKs integrationt tests are set to run against
kubectl port-forward svc/haproxy-node1-svc -n "${SOLO_NAMESPACE}" 50211:50211 &

// Optional mirror node deploy
npm run solo mirror-node deploy

// Optional hashscan - requires mirror node deploy
kubectl port-forward svc/fullstack-deployment-hedera-explorer -n "${SOLO_NAMESPACE}" 8080:80 &
