v.0.8.1

Fixed:
Bug: Python 2 - As division is Integer in Python 2: Free Mem, Avail are shown as 0%
Bug: Python 2 - Size of root is rounded and Free inodes displayed as 0% due to Python 2 integer's division

RELEASE NOTES:
Still those bugs pending for Python 2:

Extending Unit Testing for fileutils.py to more cases and fixing test_string.
FileUtils.strings method now uses read_binary instead of opening the file and doing all the job itself.

Added basic Unit Test for CTOP with iterations mode 3, 2 and 1.

Updated library fileutils and test_fileutils. Update is to methods not used by CTOP. Maintenance update.

Fixes #50

v.0.8.8

Added to Dockerfile:
# This will make sure printing in the Screen when running in detached mode
ENV PYTHONUNBUFFERED=1

Added packages to sample Dockerfile:
pytest

Added Code Coverage for case in StringUtils where o_stringutils.convert_string_to_integer("") is sent an empty string.

Refactor StringUtils.convert_to_gb() to convert_kb_to_gb().

Added Unit Testing for convert_kb_to_gb().
Code Coverage from StringUtils raised to 83%.

Added Code Coverage StringUtils.get_bytes_per_second() raising Code Coverage to 89%.

Added Code Coverage StringUtils.get_percent() and added special case for division by 0. Code Coverage is 95%.

If StringUtils.get_bytes_per_second() if passed 0 as seconds, this is considered 1 second.
We avoid a Division by Zero error, and in most of cases, you want to know the allowed bandwidth, so considered that it took 1 second
will be correct.

OsUtils.update_is_in_vbox_or_amazon_or_gcp() now transforms to lowercase first, before searching.
OsUtils.update_is_in_openstack() now transforms to lowercase first, before searching.

Or
sudo docker run -it -exec --mount type=bind,source=/home/carles/Desktop/code/ctop_pro/src/ctop/,target=/ctop ubuntu /bin/bash
And installing python3 and runnint /ctop/ctop.py

Refactor to extract reading file from MemUtils.update_meminfo()

Change in osutils.get_total_and_free_space_in_gib() to get the space from round(f_total_gb ,2) instead of "%.2f" % f_total_gb

Fixed imports in test_osutils.py test_pythonutils.py test_renderblocks.py test_systemutils.py so automated tests from Jenkins work.
