While using esp_wifi_set_config, flag pmf_capable defaults to 0.
Users may not bother to enable it, which prevents connection to a
WPA3 AP. Or the AP may reset into WPA3 mode failing the re-connection.
To ensure better security, deprecate the pmf_capable flag and set it to
true internally.
This commit adds an example in NimBLE where esp32 runs a peripheral as
well as a ping request to configured IP address. This example uses
nimble host stack.
