Adding host support for json schemas in claims

[autodidaddict]

This adds support for the config_schema field in capability provider claims. It is supposed by both the internal claims cache and the KV bucket, as well as extraction from the PAR file itself.

Querying claims from the lattice (asking the host):

wash ctl get claims -o json
[warn] `wash ctl get claims` has been deprecated in favor of `wash get claims` and will be removed in a future version.

{
  "claims": {
    "claims": [
      {
        "call_alias": "",
        "caps": "",
        "config_schema": "{\"$schema\":\"https://json-schema.org/draft/2020-12/schema\",\"description\":\"wasmCloud HTTP Server Provider Link Definition configuration specfiication\",\"properties\":{\"address\":{\"default\":\"127.0.0.1:4000\",\"description\":\"An address and port combination on which to listen.\",\"type\":\"string\"},\"config_b64\":{\"description\":\"A base64 encoded version of the config_json property.

      }
    ]
  },
  "success": true
}

note that the config_schema field, as managed by the hosts, is an escaped string and not managed as raw JSON.

Querying directly from the bucket:
