Decouple Cboard from third parties

[lutangar]

• Sendgrid
• Facebook SSO
• Google SSO
• Google Analytics (is GA used by Cboard stats page ?)
• Google adsense
• Azure
  • blob storage (see Create a file system storage #2 )
  • speech
• IPinfo

I discovered yet another dependency to a third party...

@JeromeGutman could you create an IPinfo account in the name of @ERASME-GL please ?

Our current work in progress has been submitted to the CBoard community via :

• Decoupling constants and services cboard-org/cboard-api#233
• Decoupling constants and services cboard-org/cboard#1290

In the current state it allows Interpretable to move toward self hosting but it still misses :

• Discussion with CBoard community to make the configuration compatible with their work
• Documentation of the newly introduced environment variables
• Resolve security issue in Create a file system storage #2
