Remove dependency on pyaws module logger (not used)

[blakeca00]

From current version of __init__.py:

try:

    from keyup import logd
    logger = logd.getLogger(__version__)

    # set pyaws log function to keyup global logger
    import pyaws
    pyaws.logger = logger

except Exception:
    pass

OMIT lines 6 - 8. System should then default to logger instantiated above in line 4 (from logd.py module).

The following changes must be made to remove dependency on package pyaws:

1. All boto3 sessions and clients must be instantiated directly within keyup code.
2. Logger must originate from python package libtools instead of pyaws.
3. Module function get_os must be copied from package pyaws and implemented directly in keyup’s code.

Package pyaws must be removed from the following keyup modules:
