/user/limits in bits or bytes

[ro-tex]

PULL REQUEST

Overview

The /limits endpoint returns the bandwidth limits in bits per second, which is the format most people expect to see.
The /user/limits endpoint, though, returns the bandwidth in bytes per second because that is what Nginx expects to see.

This discrepancy is very confusing for users and it needs to be resolved. To that end this PR adds a new query parameter which would let Nginx request the limits in bytes (see SkynetLabs/skynet-webportal#1855) while everyone else will receive the limits in bits.

DO NOT MERGE!

Nginx is not passing the right query parameters when asking for user limits, so if we merge this right now it will get the answer in bits and interpret it in bytes.
