Remove Read and Write timeout from the daemon API server

the timeouts were added in b38b9ef
to fix golangci_lint errors, however since we have some long running
operations such as '/start', '/stop' and '/delete' which takes more
then 10 seconds to finish, it ends up with io error

this commit removes the ReadTimeout and WriteTimeout and instead set
the ReadHeaderTimeout for the server

setting ReadHeaderTimeout should prevent slowloris attacks as reported
by golangci_lint
