net/mlx5: add hardware queue object context dump

Add debug capability to mlx5 PMD to dump SQ/RQ/CQ HW object context for
a given port/queue. The context dump can provide some real-time

net/mlx5: add testpmd commands for GENEVE TLV parser

Add GENEVE TLV parser support for mlx5 testpmd using following commands:

1. Add single option to the global option list:

testpmd> mlx5 set tlv_option class (class) type (type) len (length) \
offset (sample_offset) sample_len (sample_len) \
class_mode (ignore|fixed|matchable) \
data (0xffffffff|0x0 [0xffffffff|0x0]*)

2. Remove several options from the global option list:

testpmd> mlx5 flush tlv_options max (nb_option)

3. Print all options which are set in the global option list so far:

testpmd> mlx5 list tlv_options

4. Create GENEVE TLV parser for specific port using option list which
are set so far:

testpmd> mlx5 port (port_id) apply tlv_options

5. Destroy GENEVE TLV parser for specific port:

testpmd> mlx5 port (port_id) destroy tlv_options

net/mlx5: fix testpmd quit with available desc threshold

When testpmd quit with mlx5 avail_thresh enabled, a rte timer handler
delays to reconfigure rx queue to re-arm this event. However at the same
time, testpmd is destroying rx queues.
It's never a valid use case for mlx5 avail_thresh. Before testpmd quit,
user should disable avail_thresh configuration to not handle the events.
This is documented in mlx5 driver guide.

To avoid the crash in such use case, check port status, if it is not
RTE_PORT_STARTED, don't process the avail_thresh event.

net/mlx5: add test for remote PD and CTX

Add mlx5 internal option in testpmd similar to run-time function
"port attach" which adds another parameter named "socket" for attaching
port and add 2 devargs before.

The arguments are "cmd_fd" and "pd_handle" using to import device
created out of PMD. Testpmd application import it using IPC, and updates
the devargs list before attaching.

These arguments were added in
the commit 9d936f4f1a5e ("common/mlx5: support remote PD and CTX")

The syntax is:

testpmd> mlx5 port attach (identifier) socket=(path)

Where "path" is the IPC socket path agreed on the remote process.

app/testpmd: add host shaper command

Add command line options to support host shaper configure.
- Command syntax:
mlx5 set port <port_id> host_shaper avail_thresh_triggered <0|1> rate
<rate_num>

- Example commands:
To enable avail_thresh_triggered on port 1 and disable current host
shaper:
testpmd> mlx5 set port 1 host_shaper avail_thresh_triggered 1 rate 0

To disable avail_thresh_triggered and current host shaper on port 1:
testpmd> mlx5 set port 1 host_shaper avail_thresh_triggered 0 rate 0

The rate unit is 100Mbps.
To disable avail_thresh_triggered and configure a shaper of 5Gbps on
port 1:
testpmd> mlx5 set port 1 host_shaper avail_thresh_triggered 0 rate 50

Add sample code to handle rxq available descriptor threshold event, it
delays a while so that rxq empties, then disables host shaper and
rearms available descriptor threshold event.
