python: use explicit binaries version

Specify explicit Python 3 python3 and pip3 binaries everywhere to make
commands more portable.

ci: remove source code with script

Remove connector source code for pure install tests with Python script.
Python was chosen since it would work both on Windows and Linux.

cd: pack pip package

Pack source code and wheel file with Github Actions. Result is stored as
artifact.

Part of #198

cd: publish pip package

Publish pip package on tag.

To test, comment "run only on tags" condition, change PYPI_REPO
to testpypi and use ${{ secrets.TEST_PYPI_TOKEN }} as PYPI_TOKEN. You
also need to remove 5dfdae5 commit
changes about scm version and set some constant version: using local
version identifiers [1] is not allowed by test.pypi.org.

cd: pack RPM package

New RPM spec is based on RHEL RPM guide for Python packages [1] merged
with results of python3 setup.py bdist_rpm --spec-only.

Beware that RPM name is changed based on recommendations for all
mainstream distributives (for example, see [2]). Binary RPM is named
python3-tarantool and source RPM is named python-tarantool. Before the
patch they both were called tarantool-python (even though there wasn't
new RPM releases since 0.6.5).

RPM is suitable for distributives with Python 3.7 or newer. See [3]
about pre-Python 3.7 systems support.

test: make host more portable

Docker container localhost resolve fails to connect test suites
to test Tarantool instances.

ci: run tests with RPM package

See [1] about CentOS support. Fedora 37 is not tested yet since there is
no Tarantool for it.

to https://rws-dev.tarantool.org.

Closes #164, part of #198

cd: pack deb package

New deb spec files are based on stdeb plugin generated files [1] and
Debian Style Guide for Packaging Python Libraries [2].

Beware that RPM name is changed based on recommendations for all
mainstream distributives [2]. deb files are named with python3-tarantool
prefix. Before the patch they were called tarantool-python (even though
there wasn't new deb releases since 0.6.5).

deb is suitable for distributives with Python 3.7 or newer. See [3]
about pre-Python 3.7 systems support.

Since deb requires changelog consistency to build, we generate
a changelog entry for all nightly CI builds.

fix: timezone offset with old pytz and pandas

It seems that older pandas and pytz distributions (for example, ones
from Debian 10 deb repositories) are prone to issues when pytz timezone
offset ignores current datetime value [1]. Using explicit localize is
both valid in modern version and fixes the bug for older ones.

included here.

Hi. Thank you for the patchset.
Great work.

• "Specify explicit Python 3 python3 and pip3 binaries everywhere to make commands more portable." - why does it make commands more portable?

See several comments bellow.

"Specify explicit Python 3 python3 and pip3 binaries everywhere to make commands more portable." - why does it make commands more portable?

python3 is Python 3 binary for all systems which have Python 3 installed. For some configurations, python is python3 by default, sometimes you can make python to be python3 by installing python-is-python3 package or by messing with aliases (but I don't think we should enforce users to do so), but sometimes system has python2 for python. Same goes for pip (and I think I've met the case when python was python3 but pip was pip for Python 2).

Since our code supports only Python 3, we must ensure that everything runs with Python 3 only.
