emacs: allow opting out of notmuch's address completion

Browse source 
IMO Notmuch should not override the default completion mechanism by
default, at least not globally. But since users are already used to
this behavior it is probably too late to change it. Do the next best
thing and at least allow users to opt out.

If this is a string, then that string should be an external

Alternatively, it can be the symbol `internal', in which case
internal completion is used; the variable
`notmuch-address-internal-completion' can be used to customize
this case.
If this is the symbol `internal', then an implementation is used
that relies on the \"notmuch address\" command, but does not use
any third-party (i.e. \"external\") programs.
Finally, if this variable is nil then address completion is
disabled."
If this is the symbol `as-is', then Notmuch does not modify the
value of `message-completion-alist'. This option has to be set to
this value before `notmuch' is loaded, otherwise the modification
to `message-completion-alist' may already have taken place. This
setting obviously does not prevent `message-completion-alist'
from being modified at all; the user or some third-party package
may still modify it.
Finally, if this is nil, then address completion is disabled."
