Description

Current SlackTransport implementation has API method hardcoded: chat.postMessage

        $response = $this->client->request('POST', 'https://'.$this->getEndpoint().'/api/chat.postMessage', [
            'json' => array_filter($options),
            'auth_bearer' => $this->accessToken,
            'headers' => [
                'Content-Type' => 'application/json; charset=utf-8',
            ],
        ]);

chat.update API method requires 2 parameters: transport (already available in SlackOptions) and ts (should be added).
Then based on these options API method can be selected.

This feature can be used to update slack messages on entity status updates, etc. For example SentMessage id can be saved in the database when message is first sent to the slack, and later can be used to update the same message.

WDYT?
