Remove GetVersions from Connection interface

[colin-axner]

Summary

Remove GetVersions from the connection interface.

Problem Definition

This function is unused as an interface. The only calls to this function use the concrete connection type. The connection interface only exists to avoid import cycles (we only use one concrete connection type).

Proposal

Remove GetVersions from the connection interface. Leave the function within the ConnectionEnd implementation. Please include a changelog entry. This change doesn't need to be backported
