Ver 2.0,1; Nginx based endpoint protection

[ret7020]

Write nginx rules to protect some endpoints from bruteforce like attacks:

• /auth/login from bruteforce
• /auth/me from server overload, because it use crypto functions to validate token
• /notifications polling (maybe rewrite polling architect to use global state and Streaming response)

Current limit to /api/login kills that endpoint
