DESCRIPTION
    This class implements Riap::HTTP client.

    This class uses Log::Any for logging.

ATTRIBUTES
    *   realm => STR

        For HTTP basic authentication. Defaults to "restricted area" (this
        is the default realm used by Plack::Middleware::Auth::Basic).

    *   user => STR

        For HTTP basic authentication.

    *   password => STR

        For HTTP basic authentication.

METHODS
  PKG->new(%attrs) => OBJ
    Instantiate object. Known attributes:

    *   retries => INT (default 2)

        Number of retries to do on network failure. Setting it to 0 will
        disable retries.

    *   retry_delay => INT (default 3)

        Number of seconds to wait between retries.

    *   lwp_implementor => STR

        If specified, use this class for http LWP::Protocol::implementor().
        For example, to access Unix socket server instead of a normal TCP
        one, set this to 'LWP::Protocol::http::SocketUnix'.

    *   log_level => INT (default 0 or from environment)

        Will be fed into Riap request key 'loglevel' (if >0). Note that some
        servers might forbid setting log level.

        If TRACE environment variable is true, default log_level will be set
        to 6. If DEBUG, 5. If VERBOSE, 4. If quiet, 1. Else 0.

    *   log_callback => CODE

        Pass log messages from the server to this subroutine. If not
        specified, log messages will be "rethrown" into Log::Any logging
        methods (e.g. $log->warn(), $log->debug(), etc).

  $pa->request($action => $server_url, \%extra_keys) => $res
    Send Riap request to $server_url. Note that $server_url is the HTTP URL
    of Riap server. You will need to specify code entity URI via "uri" key
    in %extra_keys.

    %extra_keys is optional and contains additional Riap request keys
    (except "action", which is taken from $action).

FAQ
TODO
    *   attr: hook/handler to pass to $ua

    *   attr: use custom $ua object
