Draft: emc-test-suite: update setup scripts for remote-station to Yocto Kirkstone

This MR is the second part of proof of concept for https://secogroup.atlassian.net/browse/YT-191 task.

This MR is auxiliary and is in charge of adjustment of various scripts focused on remote station. Following changes are introduced:

• actualized CAN and Bluetooth echo scripts, which are launched on remote, to Kirstone;
• renamed rs232 echo scripts to get rid of # symbol;
• separated a configuration from the code of setup script by isolating it in base configuration file;
• added machine specifics configuration files which may be used to replace a base configuration in the sub-package in build pipeline;
• added a systemd service for launching an "echo" test services;
• added a systemd service in charge of setup of remote station;
• added instructions to README on how to launch the setup scripts;
• renamed emc-test-remote-santoka-setup.sh to emc-test-remote-setup.sh and improve it:
  • updated to Kirkstone;
  • added "--disable" argument to stop running echo services and to clean up;
  • added arguments to specify system descriptors (/dev/tty...) for RS232 and RS485 ports which will be used for testing;
  • added an argument to specify a custom configuration file instead of config provided by the sub-package ("base" and "machine"-specific).

The first part of the PoC with introduction of sub package can be found in following MR: seco-ne/yocto/layers/meta-seconorth-distro!807
