This allows to configure the Wasm module, e.g

  ./configure wasm --include-path=/path/to/wasmtime-v11.0.0-x86_64-linux-c-api/include --lib-path=/path/to/wasmtime-v11.0.0-x86_64-linux-c-api/lib --rpath

--rpath as above says to set the rpath to the value of --lib-path. You
can alternatively specify a directory to use as the rpath. Or simply
omit the option to not have an rpath set.

This is mostly useful for during development where you may not have the
Wasmtime stuff installed to system directories or you want to test with
newer/different versions.

See ./configure wasm --help for a full list of options.

This commit introduced the basic URI rewrite. It allows users to change request URI. Note the "rewrite" option ignores the contained query if any and the query from the request is preserverd.
An example:
"routes": [
    {
        "match": {
            "uri": "/v1/test"
        },
        "action": {
            "return": 200
        }
    },
    {
        "action": {
            "rewrite": "/v1$uri",
            "pass": "routes"
        }
    }
]
