Cluster monitoring does not work when node name has colon ":" character

Issue Summary

The clustering monitoring page does not work in case the node name has colon ":" character hence not providing CPU/Memory/Uptime information.

Steps to Reproduce

1. Deploy JIRA Datacenter 8.6.1
2. In the cluster.properties file, add the node name (jira.node.id) as "test:1234"

Expected Results

• CPU/Memory/Uptime information to be displayed:
  

Actual Results

• CPU/Memory/Uptime information is not displayed:
  

Note

Scope of the problem:

• The existing Jira quick start (https://aws.amazon.com/quickstart/architecture/jira/) does not have this issue.
• only affects quick start deployments that were deployed before the 4th of June last year
• or customers who are deploying with CloudFormation from this repository: https://bitbucket.org/atlassian/atlassian-aws-deployment/src/master/.

Workaround

• Remove the colon character ":" from the node name (jira.node.id in cluster.properties file).
