Log dev team flag to metrics

[kdid]

Summary

We want to be able to sort out our own requests and testing of DC chat through metrics

Changelog

• Adds isDevTeam flag to DCAPI token
• Add is_dev_team flag to the metrics log
• Also fixes issue where Meadow's superuser tokens where not authorized for chat because they are isLoggedIn=false

Steps to Test

• Grab new tfvars: https://github.com/nulib/tfvars/blob/main/dc-api/staging.parameters#L11
• Update any dev params accordingly
• dev/deploy chat
• Run main DCAPI dev/locally
• Generate token with the isDevTeam flag set
  • You can do this by hitting https://{your-dev-env}.dev.rdc.library.northwestern.edu:3002/auth/login?goto=https://{your-dev-env}.dev.rdc.library.northwestern.edu:3002/auth/callback (and grabbing the resulting token)
• Check the auth/whoami route that the token contains the flag
• Send a chat request (through Postman)
• check the metrics log (compare with screenshot below)
• Test other types of users who should result in a false dev team flag
