Further automation for local deployments

[bsquizz]

Automate more of the local deployment steps to enable easy setup for local front-end development, this would include:

• edit the SSO url in chrome to point to local keycloak
• stand up a gateway/proxy service which sends API calls from the front-end to the mocks whenever the front-end tries to query BOP/entitlements/RBAC/etc.

Essentially, take pieces of tool.py in https://github.com/jctanner/aa-hacking/ does but make it generalized for any app team.
