Log files with non-useful information

[MIchaelMainer]

Describe the bug
We are creating log files with every call. The information in the log files are not useful and could be a potential source for data leakage if we aren't intentional with the data we emit to the logs.

An example of a login log entry:

CMD-LOG-LINE-BEGIN 16644 | 2021-05-10 15:59:38,789 | INFO | mg_command_data_logger | command args: login --scopes {} --debug
CMD-LOG-LINE-BEGIN 16644 | 2021-05-10 15:59:51,130 | INFO | mg_command_data_logger | exit code: 0

Log entries:

To Reproduce
Steps to reproduce the behavior:

1. Run any command.
2. Go to c:\users\{user}\.mg\commands

Expected behavior
We only emit log files when a user has opted-in to logging. The log files should contain useful information.
