🐛 Public Hostnames "Path" is appended to Service URL

Opening this as a cloudflared issue at the suggestion of @ranbel. See also: https://github.com/cloudflare/cloudflare-docs/issues/7264

**Describe the bug**

The `Public Hostname Page` for a Cloudflare Tunnel has three fields:

| (optional) Subdomain | (required) Domain | (optional) Path |
| --------------------- | ------------------ | ---------------- |

As the documentation clearly states, this can be used to expose http resources like so:

```
subdomain.domain.com >> http://localhost:1234
```

However, it seems that the beheviour is currently such that instead of:

```
subdomain.domain.com/path1 >> http://localhost:1234
subdomain.domain.com/path2 >> http://localhost:5678
```

we get:

```
subdomain.domain.com/path1 >> http://localhost:1234/path1
subdomain.domain.com/path1 >> http://localhost:1234/path2
```

**To Reproduce**
Steps to reproduce the behavior:
1. Follow [the Cloudflared documentation](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/routing-to-tunnel/) to expose any HTTP resources to the Internet via a public hostname.

**Expected behavior**

```
subdomain.domain.com/path1 >> http://localhost:1234
subdomain.domain.com/path2 >> http://localhost:5678
```
