Add HTTP proxy base path/prefix configuration option for UI

[krocans]

Currently it's impossible to put influxdb UI behind reverse proxy in non-root location. For example nginx configuration like this is not working location /flux/ { proxy_pass http://127.0.0.1:8086/; } Influxdb is always returning root-based URLs in responses eg. <script src="/a35d56ccdc.js"> and that breaks proxy passing.

Please add some config option like http-ui-base-path which "relocates" UI access base URL.

Expected behavior If configuration option is set like http-ui-base-path: 'flux/'.

• Influxdb returns UI content on request http://127.0.0.1:8086/flux/
• Probably redirects request '/' to '/flux/'
• Returns all paths un UI HTMLs prefixed wit this path eg. <script src="/flux/a35d56ccdc.js">

This has popped up in a couple of other places as well...linked below for reference:

• Question asked on the InfluxDB community forums: https://community.influxdata.com/t/nginx-reverse-proxy-with-influxdb2/20689
• Feature request for a similar option in Kapacitor: https://github.com/influxdata/kapacitor/issues/2478

This seems to be a duplicate of https://github.com/influxdata/influxdb/issues/15721.

Is there any way to speed up such a basic feature? Is there any reason why this was not done properly in the first place?

There's no need to shout.

+1 We need the base URL to use an Nginx reverse proxy, just like OP
