When performing an *aptly snapshot pull*, users might list dependency
versions that can potentially match multiple packages in the source
snapshot. However, the current implementation of the 'snapshot pull'
command only allows one package to be pulled from a snapshot at a time
for a given dependency.
The newly implemented all-matches flag allows users to pull all the
matching packages from a source snapshot, provided that they satisfy the
version requirements indicated by the dependencies.
The all-matches flag defaults to false and only produces the described
behaviour when it is explicitly set to true.
This enables us to return the latest version of a package when no version is specified rather than the oldest.
Therefore, we don't need to modify the search algorithm to return the latest version of a package.
