[Feature]: Configuring whether path prefix is stripped for services w/o a gateway

[jvstme]

Problem

Currently, when a service is run without a gateway, dstack strips the /proxy/services/<project>/<run> path prefix before forwarding the request upstream. So /proxy/services/<project>/<run>/ becomes /, /proxy/services/<project>/<run>/a/b/c becomes /a/b/c, etc.

This allows API-only services to work out of the box. This also works for web apps that allow configuring the root path but don't expect to receive it in requests, e.g. ASGI apps served with uvicorn.

However, many popular web apps do expect to receive the path prefix in requests if it is configured as their root path. Such apps don't currently work without a gateway.

Solution

Add a boolean service configuration option to control whether the path prefix is stripped, e.g. strip_prefix. The default is strip_prefix: true (current behavior). The option is ignored when running with a gateway.
