Tagging for data sources + hosts

Customers would like to be able to Tag their Instances or Hosts

Some example tags that customers might choose to apply are:

• App=Customer Portal
• Environment=Prod
• OS=Amazon Linux 2
• Project=Customer Portal
• Owner=Joe Bloggs
• Cost Center=DigitalOps
• Customer=Cust1
• Cluster=OracleRAC01
• Version=1.0.2

These tags should be informational when displayed on the Instance details screen.

On the instances overview screen, tags could be used as a way of filtering down the list of instances.
