Description

When cache engine tries to discover existing cache by checksum, it sends get request. 
This request is normally getting 404s, because cache is not guaranteed to exist.
It's a normal situation and exception should not be printed in such case as it meaninglessly pollutes logs:

Need to create method similar to RemoteCacheRepositoryImpl#getResourceContent, but getResourceContentQuiet and use it when probing buildinfo.xml. the method should not log exceptions
