### Changelogs
#### Template message feature
Now we are supporting template message feature!

A message with valid `extendedMessagePayload.template` value will be
displayed with `TemplateMessageItemBody`

* Added new ui components:
  * `MessageTemplate`
  * `TemplateMessageItemBody`
  * `FallbackTemplateMessageItemBody`
  * `LoadingTemplateMessageItemBody`
