Systemd.exec supports configuring the runtime directory of a service
via RuntimeDirectory=. This creates the directory with the necessary
permissions which actual service may not have if running in container.
The change to DPDK is to look for the environment RUNTIME_DIRECTORY
first and use that in preference to the fallback alternatives.

This patch adds the option --list (-l) to dpdk-telemetry.py which will
print all of the available file-prefixes for DPDK processes that have
telemetry enabled.
The prefixes will also be printed if the user passes an incorrect prefix
in the --file-prefix (-f) option.

When a user runs the dpdk-telemetry script and fails to connect because
the socket path does not exist, run a scan for possible sockets that
could be connected to and inform the user of the command needed to
connect to those.
For example:
$ ./dpdk-telemetry.py -i4
Connecting to /run/user/1000/dpdk/rte/dpdk_telemetry.v2:4
Error connecting to /run/user/1000/dpdk/rte/dpdk_telemetry.v2:4
Other DPDK telemetry sockets found:
- dpdk_telemetry.v2 # Connect with './dpdk-telemetry.py'
- dpdk_telemetry.v2:2 # Connect with './dpdk-telemetry.py -i 2'
- dpdk_telemetry.v2:1 # Connect with './dpdk-telemetry.py -i 1'

For processes run using "in-memory" mode sharing the same runtime dir,
we add support for connecting to the separate instance sockets created
using ":1", ":2" etc. via new "-i" or "--instance" argument. Add details
on connecting to separate instances to the telemetry howto document.

When the input to the script is coming from a device which is not a TTY
then we become less verbose and skip the prompts and helpful messages
about what is happening.

To allow the script to take queries from input pipes e.g. "echo
/ethdev/stats,0 | dpdk-telemetry.py", we need to handle the case of EOF
correctly without crashing with an exception. Do this by using a
try-except block around the input handling.

When the dpdk-telemetry client connects to a DPDK instance, we can use the
PID provided in the initial connection message to query from /proc the name
of the process we are connected to, and display that to the user. We use
the "cmdline" procfs entry for the query since that is available on both
Linux and FreeBSD (assuming procfs is mounted on the BSD instance).

Currently the dpdk-telemetry.py script connects to all running DPDK apps
consecutively. With the addition of this file-prefix argument, we can limit
the amount of information returned providing improved consumability and
precision to the user.

This patch adds a python script that can be used with the new telemetry
socket. It connects as a client to the socket, and allows the user send
a command and see the JSON response.
The example usage below shows the script connecting to the new telemetry
socket, and sending three default telemetry commands entered by the user.
The response for each command is shown below the user input.
