Krishna T 25d0f87b3c net: dhcp: Add support for restarting DHCP If a L2 link has been established, then the DHCP is taking too long as it has to go through its capped exponential backoff timers to trigger discover (The DHCP starts immediately during init, this is itself wrong, it should start on a link UP notification) that delays the DHCP for few seconds to a minute. And if we do stop and start DHCP then also it goes through the initial delays (though configurable), which is also not ideal. Add support for restarting DHCP without any delay, i.e., release and send discover immediately. This is also useful in case L2 switches to a different subnet, in this case Zephyr doesn't restart DHCP automatically, this API can be used by L2 apps/drivers to restart DHCP to get new subnet IP.

Wi-Fi sample
############

Overview
********

This sample allows testing Wi-Fi drivers for various boards by
enabling the Wi-Fi shell module that provides a set of commands:
scan, connect, and disconnect.  It also enables the net_shell module
to verify net_if settings.

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

Verify the board and chip you are targeting provide Wi-Fi support.

For instance you can use TI's CC3220 by selecting the cc3220sf_launchxl board.
