Expose Template TagHelper configuration options for the Chat

[alestoya]

Overview

In order to set a template, you would have to use either the {templateName}-template-id or {templateName}-handler TagHelper attributes:

<kendo-chat name="chat" message-template-handler="getMessageLayout">
</kendo-chat>

It would be beneficial if the template component could be leveraged directly within the existing TagHelper structure of the Chat TagHelper via the TagHelpers. For instance:

<kendo-chat name="chat">
            <message-template>
                <h3>My Template</h3>
            </message-template>
            <files-template>
                <p>Test Test</p>
                <kendo-button name="myBtn">Click Here</kendo-button>
            </files-template>
</kendo-chat>

The affected options will be:

• filesTemplate
• messageGroupTemplate
• messageReferenceTemplate
• messageTemplate
• suggestedActionsTemplate
• suggestionsTemplate
• timestampTemplate

Current behavior

The aforementioned Chat component TagHelpers do not expose an additional Template Component TagHelper integration for its template options.

Expected/desired behavior

The aforementioned Chat component TagHelpers should expose an additional Template Component TagHelper integration for its template options.
