Implement rename family 

Implement rename, renameat, renameat2

Added new rcp "insert_node" to insert new metadentry into the metadata DB.
This call differs from the "mk_node" because it will insert the metadata
received from the caller instead of generating them assuming that they
have been generated previously.

It can be used to move entries between metadata nodes
