I'd like to remove the following ports that were needed for spyder 4 and 
are no longer needed now that we have spyder 5 in the tree.

The ports themselves are dead with spyder having moved to using active 
forks of each of the below:

- devel/py-pyls-black
- devel/py-python-language-server
- net/py-python-jsonrpc-server

ok to remove these?
