+Warn if snakemake-storage-plugin-http is installed and patch it to refuse all URLs.
+
+Since cached-http now accepts all HTTP(S) URLs, having snakemake-storage-plugin-http
+installed at the same time causes Snakemake to raise "Multiple suitable storage
+providers found". This module detects that situation, warns the user, and patches the
+HTTP plugin to refuse every URL so that cached-http wins unconditionally.
