Support different base path for UI/API

[giskou]

It would be nice to be able change the base path of the UI/API so that it can be served behind a proxy,
or even like this (fabio proxying itself):
+ route add proxy /proxy http://192.168.1.1:9998/ tags "registrator" opts "strip=/proxy"
without redirecting to /routes

That shouldn't be too difficult.

Any plan to tackle this?

I will have a look but there's no current development on this feature. Always a community PR is welcome.

@tristanmorgan I have implemented this, not yet fully tested though. I need 1-2 days to clean/test my changes and will share my PR
