The detection of registry modules will have to happen in mutliple
phases. The go-getter interface requires that the detector return the
final URL, while we won't know that until we verify which version we
need. This leaves the regisry sources broken, to be re-integrated in a
following commit.
wire up HTTP so we can test the mock discovery service
test lookupModuleVersions
Add a versions endpoint to the mock registry, and use that to verify the
lookupModuleVersions behavior.
lookupModuleVersions takes a Disco as the argument so a custom Transport
can be injected, and uses that transport for its own client if it set.
test looking up modules with default registry
Add registry.terrform.io to the hostname that the mock registry resolves
to localhost.
ACC test looking up module versions
Lookup a basic module for the available version in the default registry.
Adds basic detector for registry module source strings. While this isn't
a thorough validation, this will eliminate anything that is definitely
not a registry module, and split out our host and module id strings.
lookupModuleVersions interrogates the registry for the available
versions of a particular module and the tree of dependencies.
