This patch adds telemetry as a dependecy to all applications. Without these
changes, the --telemetry flag will not be recognised and applications will
fail to run if they want to enable telemetry.

This patch adds functionality to enable/disable the selftest.
This functionality will be extended in future to make the
enabling/disabling more dynamic and remove this 'hardcoded' approach. We
are temporarily using this approach due to the design changes (vdev vs eal)
made to the library.

This patch adds functionality to create a JSON message in
order to send it to a client socket.
When stats are requested by a client, they are retrieved from
the metrics library and encoded in JSON format.

This patch adds functionality to update the statistics in
the metrics library with values from the ethdev stats.
Values need to be updated before they are encoded into a JSON
message and sent to the client that requested them. The JSON encoding
will be added in a subsequent patch.

This patch adds the parser file. This is used to parse any
messages that are received on any of the client sockets.
Currently, the unregister functionality works using the parser.
Functionality relating to getting statistic values for certain ports
will be added in a subsequent patch, however the parsing involved
for that command is added in this patch.
Some of the parser code included is in preparation for future
functionality, that is not implemented yet in this patchset.

This patch introduces clients to the telemetry API.
When a client makes a connection through the initial telemetry
socket, they can send a message through the socket to be
parsed. Register messages are expected through this socket, to
enable clients to register and have a client socket setup for
future communications.
A TAILQ is used to store all clients information. Using this, the
client sockets are polled for messages, which will later be parsed
and dealt with accordingly.
Functionality that make use of the client sockets were introduced
in this patch also, such as writing to client sockets, and sending
error responses.

This patch adds the telemetry UNIX socket. It is used to
allow connections from external clients.
On the initial connection from a client, ethdev stats are
registered in the metrics library, to allow for their retrieval
at a later stage.

This patch adds the infrastructure and initial code for the telemetry
library.
The telemetry init is registered with eal_init(). We can then check to see
if --telemetry was passed as an eal option. If --telemetry was parsed, then
we call telemetry init at the end of eal init.
Control threads are used to get CPU cycles for telemetry, which are
configured in this patch also.
