Apikey generation and use in cli

[AymericCadier]

Responding to the #279 issue , dealing with Apikeys (jwt).

• Provides an Html view where logged in users can generate Tokens, with a chosen lifespan in milliseconds. View is createToken.html , and is accessible in the js/index.html .
• Added an option in the cli/damas : Users can now bypass the signin procedure. They can precize " --apikey <api_key> " (with api_key being the token generated by the view mentionned above) before their command, which allows them to do operations (such as a search, create, ...) , without having to sign in. Since it is an option, users can still sign in and providing an apy key is not mandatory .
