chore: Use --no-cache-dir flag to pip in Dockerfiles, to save space Using "--no-cache-dir" flag in pip install ,make sure dowloaded packages by pip don't cached on system . This is a best practise which make sure to fetch ftom repo instead of using local cached one . Further , in case of Docker Containers , by restricing caching , we can reduce image size. In term of stats , it depends upon the number of python packages multiplied by their respective size . e.g for heavy packages with a lot of dependencies it reduce a lot by don't caching pip packages.

Add beautifulsoup4 as a dependency So using filters like `beautify` won't result in the following error: ``` Traceback (most recent call last): File "/usr/lib/python3.8/site-packages/urlwatch/handler.py", line 120, in process data = FilterBase.process(filter_kind, subfilter, self, data) File "/usr/lib/python3.8/site-packages/urlwatch/filters.py", line 180, in process return filtercls(state.job, state).filter(data, subfilter) File "/usr/lib/python3.8/site-packages/urlwatch/filters.py", line 276, in filter raise ImportError('Please install BeautifulSoup') ImportError: Please install BeautifulSoup ``` 2021-04-08 14:53:02 +00:00			`cssselect \`
