doc: announce restrictions in telemetry naming

Browse Source 
Following discussion on-list [1], we will look to limit the allowed
characters in names for items in telemetry. This will simplify the
escaping needed for JSON output, or any future output formats. The lists
will initially be minimal, since expansion to allow more characters can
be done without affecting compatibility, while reducing the set cannot.
