doc: announce restrictions in telemetry naming

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.

* metrics: The function ``rte_metrics_init`` will have a non-void return
in order to notify errors instead of calling ``rte_exit``.
* telemetry: The allowed characters in names for dictionary values
will be limited to alphanumeric characters
and a small subset of additional printable characters.
This will ensure that all dictionary parameter names can be output
without escaping in JSON - or in any future output format used.
Names for the telemetry commands will be similarly limited.
The parameters for telemetry commands are unaffected by this change.
* raw/ioat: The ``ioat`` rawdev driver has been deprecated, since it's
functionality is provided through the new ``dmadev`` infrastructure.
To continue to use hardware previously supported by the ``ioat`` rawdev driver,
