feat(LSP): Reorganise PyLSP blocks of code

Although the block of code moved is programmatic configuration taking
place before the actual on/off of settings (which could be interpreted
as metadata config), the block of code in question had nothing to do
with the setting of other LSPs than PyLSP.

The whole block is for pre-installing plugins for PyLSP server, or its
plugins'.
