Remove useless files

[hardion]

There are non generic script that should not be part of this project.

The setup.py will also have to be modified to remove the entry_points that are no longer available.

Is ./dsconfig/remove.py still valid ? It seems to be broken.

Traceback (most recent call last):
  File "./dsconfig/remove.py", line 6, in <module>
    from utils import (ObjectWrapper, decode_dict, get_dict_from_db,
ImportError: cannot import name decode_dict

@hardion @AntoineDupre Can you please have a look at this? We'll be continuing dsconfig work in our next sprint, migrating to Python 3.

This appears to have been partly addressed by #14. Although that PR didn't remove dsconfig/excel.py. Also, the setup.py file still points to entry points that no longer exist.

lib-maxiv-dsconfig/setup.py

Lines 22 to 25 in a31f67a

	entry_points={
	"console_scripts": ["xls2json = dsconfig.excel:main",
	"csv2json = dsconfig.callcsv:main",
	"json2tango = dsconfig.json2tango:main"]

In the develop branch, we would need to remove at least csv2json = dsconfig.callcsv:main. In this PR, we would also need to remove xls2json = dsconfig.excel:main.
