[PATCH v4 5/9] remote-odb: add remote_odb_reinit()

[Christian Couder <christian.couder@gmail.com>]

From: Christian Couder <christian.couder@gmail.com>

We will need to reinitialize the remote odb configuration
as we will make some changes to it in a later commit when
we will detect that a remote is also a remote odb.
