send-email: add --[no-]outlook-id-fix option

Add an option to allow users to specifically enable or disable
retrieving the Message-ID from the Outlook SMTP server. This can be used
for other hosts mimicking the behaviour of Outlook, or for users who set
a custom domain to be a CNAME for the Outlook SMTP server.

While at it, lets also add missing * in description of --no-smtp-auth.

--[no-]outlook-id-fix::
Microsoft Outlook SMTP servers discard the Message-ID sent via email and
assign a new random Message-ID, thus breaking threads.
+
With `--outlook-id-fix`, 'git send-email' uses a mechanism specific to
Outlook servers to learn the Message-ID the server assigned to fix the
threading. Use it only when you know that the server reports the
rewritten Message-ID the same way as Outlook servers do.
+
Without this option specified, the fix is done by default when talking
to 'smtp.office365.com' or 'smtp-mail.outlook.com'. Use
`--no-outlook-id-fix` to disable even when talking to these two servers.
