Default ctags exclude list is unconfigurable

[ashb]

The default exclude list is unconfigurable -- which is a problem for me as I have a .../deps/... folder that I don't want to ignore.

Where this this come from, cos it appears to have a lot of java things that are just not common in my experience of developing python.

I'd propose removing these all from the hard-coded config file https://github.com/neoclide/coc-python/blob/master/resources/ctagOptions and then moving them to in to the (default) config of pythonSettings.workspaceSymbols.exclusionPatterns -- that way they can be configurable.

My temporary work around for this was to add "" as a exclude pattern on the config, which then causes ctags to reset it's exclude list when it encounters it, and then add back in the ones I wanted.
