Rohan Challa 62a9628863 internal/lsp: use the -modfile flag to update a different go.mod file
In the upcoming Go 1.14 release, there is an introduction of the -modfile
flag which allows a user to run a go command but choose where to direct the
go.mod file updates. The information about this can be found here: golang/go#34506.

This change starts setting up the infrastructure to handle the seperate modfile
rather than keep changing a user's go.mod file. To support versions of Go that are
not 1.14, we run a modified "go list" command that checks the release tags to see
if 1.14 is contained.

Updates golang/go#31999
