com.fasterxml.clustermate.service.util.BufferBackedInputStream
Helper class that can be used to expose current contents of a {@link StreamyBytesMemBuffer} as {@link InputStream}. Assumption is that only content that exists should be exposed; and that once it is consumed, we'll consider stream to be closed: this is an alternative to blocking.
