added cmd fields for various plugins for example lspinstaller+lspconfig gets loaded only when a file opened but their commands can be run before a file is opened so I additionally lazy loaded them on their cmds too
removed nvim-gps as nvim-navic or winbar.nvim will be added when v0.8 neovim releases. Removed lsp signature as I was able to emulate showing args with the default signature help() window
