Add yotta config parse

[PrzemekWirkus]

Changes

• Add yotta_config.json parsing support.
  • yotta_config::mbed-os::stdio::default-baud setting read.
• Change dafault yotta connfiguration baudrate (default-baud) to 115200.

Example yotta configuration with baudrate

{
  "minar": {
    "initial_event_pool_size": 50,
    "additional_event_pools_size": 100
  },
  "mbed-os": {
    "net": {
      "stacks": {
        "lwip": true
      }
    },
    "stdio": {
      "default-baud": 9600
    }
  },
}

Dependencies

This feature is using extended port configuration in mbed-host-tests

• Updates to plugin system and serial port configuration options htrun#34 and exact related commit
• ARMmbed/htrun@a0d5297

Implications

mbedhtrun will be called with a baudrate added to serial port command line switch, here -p COM172:9600:

mbedhtrun -d G: -p COM172:9600 -f ".\core-util-test-functionpointer.bin" -C 4 -c shell -m K64F

See example call for one host test execution:

mbedgt: mbed-host-test-runner: stopped
mbedgt: mbed-host-test-runner: returned 'OK'
mbedgt: test on hardware with target id: 0240022648cb1e77000000000000000000000000b512e3cf
        test 'core-util-test-eventhandler' ..................................................... OK in 6.75 sec

        calling mbedhtrun: mbedhtrun -d G: -p COM172:9600 -f ".\core-util-test-functionpointer.bin" -C 4 -c shell -m K64F

why is this using different paths than the imports above? (rel/abs)
