Prevent tcportal logging full request content with authorization

[ashleysmithTTD]

What Changed:

1. Added blacklist for authorization header (see loggingHelpers.ts in uid2-self-serve-portal for reference)

Test Plan:

1. Run yarn uid2 and also make sure local operator is running
2. Open Powershell ISE
3. Paste this script to add an authorization header

$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add('authorization','Bearer 123456')

Invoke-WebRequest -Uri http://localhost:3000/ -Headers $headers -Method GET 

4. Comment out line 32 in app.ts ( //app.use(getLoggingMiddleware()) to simulate the code before this PR, run the above command in ISE, and observe the authorization bearer token in the terminal logs
5. Uncomment out line 32, run the code in ISE again, and make sure the authorization header cannot be seen in the terminal logs
6. Run yarn euid and repeat steps 2-6.
