Alex Lisitsyn d0b9829eef examples: freemodbus add tcp support for common master/slave iface
Add TCP port files to provide Modbus TCP interface for communication
Add freemodbus add tcp support for common master/slave iface and tcp example based on socket API
The communication between master and slave checked for each example serial_master, serial_slave (use ModbusPoll TCP)
update tcp example according netif changes, fix ci issues
update TCP slave implementation
update example_test.py to to set IP through stdin
update API documentation
event bit instead of semahore to lock communication resource
update default options and master/slave port files

Closes https://github.com/espressif/esp-idf/issues/858
Closes IDF-452
