Add the ability for the linkage checker to provide dependency version update suggestions

For example, given a pom.xml and an artifact identifier and version range, try to find a set of dependencies which don't introduce any new linkage errors.

Example:
checkLinkage --pom=pom.xml artifact=io.grpc:grpc-core:[1.25.0, 1.27.0]

Example output:
io.grpc:grpc-core:1.27.0
io.grpc:grpc-java:1.27.0
com.google:guava:22.0
