Add support for channelData field in conversation references

[benbrown]

Description

The conversationReference type is missing fields necessary to use createConversation with MS Teams. This PR adds those fields and amends the functions so that they will work with Teams.

Specific Changes

Adds the channelData field to the conversation reference. Information in channelData may be required for operations that use references -- for example, createConversation.

Amends the adapter's createConversation method to pass through the tenant id, which is necessary for using this method with MS Teams.

Testing

• Connect a bot to Teams.
• Using a conversation reference extracted from an incoming GROUP message, use adapter.createConversation to create a new PRIVATE context.
• Use the new context to send a private message to the user. Note that it is received as a DM, instead of a reply in the group channel.

@benbrown, is there anything we need to pickup on the C# side for this?

[stevengum]

Except for my comment about botbuilder-schema, it looks fine to me! Once that bit is squared away feel free to merge.

[stevengum]

Uh-oh, this looks like it's hand-crafted! We need to chat with Dan/Jeff/someone from the other side of the house to get this change into the Swagger definitions.

Or did you regenerate the Swagger files and this code was originally missing?

[benbrown]

Shoot! You are right, I added this by hand.

[benbrown]

Perhaps this information can go into the conversationReference.channel field instead. However, that would still require a change to the schema. I'll collect some feedback and regroup.

This PR is tied to: microsoft/botbuilder-dotnet#1362

Both should be merged at the same time.

[benbrown]

OK! The service code has changed to include this new field in the schema.

We need to regenerate!

[benbrown]

I have manually made the very small schema changes. These should match any future update from swagger.

[benbrown]

Just waiting on one final tweak to the dot-net version, then we can merge both!
