Implement Network Policies

Guide found here.

Notes

• Prerequisite knowledge of how different parts of harness communicate with each other / other parts of BB will be necessary for implementation

Definition of Done

• Default deny policy for inter-package communication is implemented
• Default allow policy for intra-package communication is implemented
• Specific policies for other packages are added, i.e. SSO, database, etc.
• Only necessary connections are allowed but harness still fully functions
