feat: init api server configs with path of host

[DonCamillo72]

Reason:
If the influxdb server runs behind a reverse proxy with url e.g. "https://anyhost/influxdb" the influx-cli could not access the url because the host base path of the api url is always empty.

Idea:
The information of the base can be passed in the cli with the host parameter like this:

influx backup --host "https://anyhost/influxdb"

Implementation:
The base path is available in the parameter params.Host.Path and could be forwarded to the OperationServers of the generated client API

Hi @jeffreyssmith2nd,

do you have a schedule for the next release?

Seems a function duplicatie to #530.

But the InfluxDB team doesn't care. I can have my fork but perhaps switch to some SDK.

I remember Python SDK v1 has such path. Not sure if v2 has.

Overall, this looks relatively straightforward and like it will address the issue.

My one reservation is that it completely overrides the existing apiConfig.OperationServers[key] value. We don't lose any valuable information today (just a non-useful description), but I'm concerned this could introduce subtle issues in the future if more valuable information is already populated in the ServerConfigurations.

Would it be possible to set the URL value without overwriting everything else?

[tisonkun]

@gwossum Just to handle the path part, you can take a look at #530 which do a light prepend on constructing the final request.
