* Have exchange data collection store path.Path
Still complies with the old FullPath() string interface until we update
that.
* Pass path.Path to NewCollection for exchange
Basically fixes up errors introduced by previous commit.
* Fixup exchange recovery path indices
All exchange paths now use the path struct, meaning the service,
category, and user elements are in the standard positions.
* use path package in selector reduction (#822)
Currently, during a reduction process, scopes
compare their values to the raw split on repoRef.
This causes some brittle indexing to retrieve
values from the rr, carrying assumptions that are
difficult to track across changes. This PR trades
the string split for the paths package to better
integrate identification of the path values.
Adds some mocks and amends some error
behaviors in order to fit paths into the current
testing schema.
