The timescale clustering code so far has been written referring to the remote databases as 'servers'. This terminology is a bit overloaded, and in particular we don't enforce any network topology limitations that the term 'server' would suggest. In light of this we've decided to change to use the term 'node' when referring to the different databases in a distributed database. Specifically we refer to the frontend as an 'access node' and to the backends as 'data nodes', though we may omit the access or data qualifier where it's unambiguous. As the vast bulk of the code so far has been written for the case where there was a single access node, almost all instances of 'server' were references to data nodes. This change has updated the code to rename those instances.
