Drive Sync feature as an option

Nuxeo Drive productization current makes the customer feel like it is the main feature. It is enabled by default, it is the first topic our documentation talks about, it is how it is pitched. Until we are confident with our ability to scale the usage of Nuxeo Drive on a given server and have solved observed client side issues (see other items), we will make the “Drive Sync” feature a second class citizen. We will review Drive documentation, we will make Drive Sync a feature disabled by default and we will disable the “Sync” user action on Web UI by default. The purpose is to confidently encourage to deploy Drive for its Direct Transfer and Direct Edit capabilities while not systematically adding in customer’s users processes the use of the sync capability.
