Description: ACS Chat faces several concerns regarding the existing bot channel implementation:

• Only partial support to a subset of bot activities
• Certain properties of supported bot activities are being discarded during transit
• Inability to enrich messages for bots to consume
• Unable to propagate thread and participant metadata to bots

The way we currently implement bot channel integration is not ideal. We're reserving a space in chat message metadata that is meant to be reserved for Contoso's usage, and having json string payload in the message content.

We're introducing new message types (AzureBotActivity and AzureBotCommand) in ChatMessageType enum, enabling ACS Chat to act as transport layer so that the entire bot payload can be sent and received by Azure bots in the form of bot activity.
