Unable to connect in a proxy setup with path prefix

[Kleinjohann]

I'm running a crate cluster behind a proxy which forwards https://my.proxy:443/crate/ to internal.crate.hostname:4200. This requires me to prepend /crate/ to all paths which does not seem to be possible in crate-python.
Am I overlooking something? If not, I would be willing to develop my current hacky fix into a fleshed-out solution and contribute it in a PR.

Hi Alexander,

thank you for using CrateDB and for reporting this.

Indeed it looks like the netloc path is nailed to the root URL path /_sql by setting self.path in the client constructor without many chances to modify it. A corresponding patch to improve the situation will be well appreciated.

With kind regards,
Andreas.
