gsi_util: adding cmd_utils
Adding a run_command function to execute a host command.
Also support reading the stdout and/or stderr of the result if desired,
which might be useful for further parsing and flow decision.
A typical usage will be passing a command sequence:
cmd_utils.run_command(['echo', '123'])
It also supports running a 'shell' command, by passing a single string:
cmd_utils.run_command('echo 123', shell=True)
To get the stdout and/or stderr data, just add 'read_stdout=True' and/or
'read_stderr=True':
cmd_utils.run_command('echo 123', shell=True,
read_stdout=True, read_stderr=True),
which returns a namedtuple:
('CommandResult', 'returncode stdoutdata, stderrdata').
Note that other keyword arguments will be passed to subprocess.Popen().
e.g., the following command will change current directory to
'my_working_dir' prior to execute the command:
cmd_utils.run_command('echo 123', shell=True, cwd=my_working_dir)
More usage examples can be found in cmd_utils_unittest.py.
Also adds a run_test.py to search then run ./*tests/*_unittest.py files.
