have a walk function that can be used to generate output by

Add collector parameter to metric creation macros so that it
is possible to bind the metric to collector already at built
time.
Also add optional user_data to metric macro calls so that user
can add optional data there. This will be used by network statistics
Prometheus support in subsequent commits.

Embed "struct prometheus_metric" to individual metric like
counter, gauge, histogram and summary. This way we avoid having
a separate base pointer in specific metrict struct. We also do
not need to search the specific metric from base metric as
we can simply use CONTAINER_OF() macro to get the base metric.
This embedding means that the counter, gauge, histogram and summary
metric define macros are changed as user does not need to create a
separate "struct prometheus_metric".
Convert the tests and sample to use the new macros.
Remove also the static from metric creation macros so that user
can decide whether it needs collector to be static or not.

This is similar function as add, but will add the difference of
previous value and the new one. This can be used if we want to
periodically update the value with a new one but don't want to
keep track of the old one.

If network interface is specified in the DNS server, then send

information in the server list.
Signed-off-by: Jukka Rissanen <jukka.rissanen@nordicsemi.no>
Allow user to specify a network interface in the DNS server
list. User can append "%" and network interface name to the
DNS server to use this. If the network interface is mentioned
in the server list, then the DNS queries are sent via this network
interface.
For example setting the interfaces like this:
192.0.2.2%eth1
[2001:db8::2]:5353%ppp0
would cause the DNS queries to sent to 192.0.2.1 via eth1 in the first
example, and to 2001:db8::2 via ppp0 in the second example.

When response is received and handled, don't just clear the structure
but instead mark it as ongoing=false.
So if we later on receive a duplicate response for it, we can still
respond with Ack or Rst.
This is achieved by using release_internal_request() when we don't
expect any response for it and reset_internal_request() when we really
fill up a new request.

The sock_obj_core_dealloc() was not called if close() is called
instead of zsock_close(). This happens if POSIX API is enabled.
Fix this by calling zvfs_close() from zsock_close() and then
pass the socket number to zsock_close_ctx() so that the cleanup
can be done properly.

SNTP simple runs request iterations with exponential backoff.
If the net interface is a slower connection (ie. CAT M1 modems)
then the request will be sent but the response may take time to
be received, thus causing a timeout and another request to be sent.
Because of the nature of UDP and the fact that the same socket
(source IP/port combo) is being used for both requests, a delayed
response to the first request can be received as the response to the
second request, causing -EINVAL to be returned when the timestamps
mismatch (see subsys/net/lib/sntp/sntp.c). The solution provided
retries receiving the response when the timestamp is mismatched
(without sending an additional request).

In receiving thread, continuing the loops is based on
has_ongoing_exchanges() so it does not need atomic
coap_client_recv_active variable.
When idling, it wakes from semaphore. But there was potential
deadlock when coap_client_schedule_poll() would not signal the
semaphore, if atomic variable was already showing that it runs.
Removing the atomic variable removes this deadlock.

If send() fails, we have not technically send the CoAP retry yet, so
restore the same pending structure, so our timeouts and retry counters
stay the same.
This will trigger a retry next time the poll() return POLLOUT, so we
