When parsing URLs on Windows, assume it is a drive letter path
if the second element is a ':' character. Format the drive letter
path as a "file:///"-path prior to parsing the URL.
Fixes test failures of the following form in command on Windows:
=== RUN TestApply_plan
--- FAIL: TestApply_plan (0.00s)
apply_test.go:379: bad: 1
module download not supported for scheme 'c'
Using url.Parse to parse an absolute file path on Windows yields
a URL type where the Path element is prefixed by a slash.
For example, parsing "file:///C:/Users/user" gives a URL type
with Path:"/C:/Users/user".
According to golang.org/issue/6027, the parsing is correct as is.
The leading slash on the Path must be eliminated before any file
operations.
This commit introduces a urlParse function which wraps the url.Parse
functionality and removes the leading slash in Path for absolute file
paths on Windows.
Fixes config/module test failures on Windows.
