Ravi kumar Veeramally 3e27187e00 samples: net: coaps_client: Increase IPv6 mcast table size
Default value 2 was not enough for mcast addresses table.
Core stack adding mcast addresses on various reasons. Also
coaps_client trying to create mcast context for some purpose.
mcast address is not in lookup table, so binding fails. Add
CoAP sample related mcast address to table and then bind the
context.

Fixes #9131

CoAP over DTLS sample client
############################

Overview
********
This sample code shows a CoAP over DTLS client using mbedTLS on top of Zephyr.

Building and Running
********************

Follow the steps for testing :ref:`networking_with_qemu`.

Run the server application at samples/net/coaps_server, with the following
command:

.. code-block:: console

	$ make server

In other terminal window, run this client application at samples/net/coaps_client:

.. code-block:: console

	$ make client

You will get the following output:

.. code-block:: console

	reply: 60 45 00 01 ff 54 79 70 65 3a 20 30 0a 43 6f 64 65 3a 20 31 0a 4d

	00 00 00 00 00 (123 bytes)

From the server application directory the screen should display

.. code-block:: console

	*******
	type: 0 code 1 id 1
	*******
	connection was closed gracefully
	done

If the server does not receive the  messages, restart the app and try to connect
the client again.
