In 53370a3e2944bd699272fd78438157a1f3c64f34 we introduced a common install-instructions configuration option for both Node- and Python-based linters.
In this commit, we move this to a PinterestExternalLinter base class so the logic is not duplicated. Aside from the cleanup, this also allows us to specify default behavior for getUpgradeInstructions() so that it takes advantage of the custom install instructions, if available.
