This series of patches ensures that all the Python code base is python3 compliant
and consistent by applying the following logic:
- python3 classifier on setup.py to explicitly state our python compatibility matrix
- add UTF-8 encoding header
- correct every shebang to the same /usr/bin/env python3
- shebang is only added on scripts meant to be executed on their own (removed otherwise)
- migrate some leftover scripts from python2 to python3 with minimal QA
This work is important to prepare for a more drastic change on Python code styling
using the black formatter and the setting up of automated QA checks on Python code base.

Add a reference to a docker image that contains an "official" toolchain
for building Scylla. In addition, add a script that allows easy usage of
the image, and some documentation.

scyllatop uses a log file, if opening the file fails, the user should
get a clear response not an exception trace.
The same is true for connecting to scylla
After this patch the following:
$ scyllatop.py -L /usr/lib/scyllatop.log
scyllatop failed opening log file: '/usr/lib/scyllatop.log' With an error: [Errno 13] Permission denied: '/usr/lib/scyllatop.log'

Scylla now expose the prometheus API by default. This patch chagnes
scyllatop to use the Prometheus API, the collect API is still available.
The main changes in the patch:
* Move collectd specific logic inside collectd.
* Add support for help information.
* Add command line to configure prometheus end point and to enable
collectd.
* Add a prometheus class that collect information from prometheus.
Fixes: #1541

Sometimes the user would like to dump all the metrics into a file or
pipe it to another program, as requested in issue #1506.
This patch makes scyllatop check if stdout is connected to a TTY,
and if not - it does not fire up the fancy urwid UI but instead, just
writes all it's collected metrics to stdout.
Optionally, the user tell the program to quit after a specific
number of iterations via the -n or --iterations flag

Sometimes a metric previously reported from collectd is not available
anymore. Previously, this caused scyllatop to log and exception to the
user - which in effect destroyes the user experience and inhibits
monitoring other metrics. This patch makes ScyllaTop handle this
problem. It will display such metrics and 'not available', and exclude
them from some and average computations.
Closes issue #1287.

NOTE: scyllatop now requires the urwid library
previously, if there were more metrics that lines in the terminal
window, the user could not see some of the metrics. Now the user can
scroll.
As an added bonus, the program will not crash when the window size
changes.

When running with DEBUG verbosity, scyllatop will now log every single
value it receives from collectd. When you suspect that scyllatop is
somehow distorting values, this is a good way to check it.

Previosly if the user did not specify any metrics, scyllatop use
whatever it could find. Now we have some preset defaults which are
probably more interesting.

The 'clear' function explicitly clears the screen and repaints it which
causes really annoying flicker. Use 'erase' to make scyllatop more
pleasant on the eyes.
