Sanchayan Maity 467a660409 nvim: Drop neomake, QFGrep and vim-grepper 
Profiling with below
nvim -c 'profile start vim.log' -c 'profile func *' -c 'q'

shows that neomake adds to the start up time. Currently we only use it
for two tasks. Running hlint for Haskell and stack build asynchronously.

Use asyncdo and define a generic wrapper command for running makeprg
asynchronously. This can be used for anything as long as makeprg is
set correctly.

vim-grepper also adds somewhat to the startup time though not much. We
do not need the functionality of switching between grep tools. Here
again just use asyncdo and define a generic command for running grepprg
asynchronously.

Drop QFGrep as we can use in built Cfilter plugin for filtering the
quickfix list.

Note that all start times mentioned above are a few milliseconds not
even more than 5ms. However, we would like to be as fast as possible
and use in built functions.
