Switch to using knex migrations to set up the database, and change the database format to use integers for ids instead of strings. Also includes various improvements and bugfixes to services and the migration from legacy /data to volumes. The switch ti migrations involves a dirty hack for webpack to properly resolve the paths to the migrations js files - it uses an expression that webpack can't resolve, so we hardcode it to a value and use the ContextReplacementPlugin to make that value resolve to the migrations folder. The downsides to this approach are: - a change in knex code would break this - the migration code is added twice to the supervisor image: once in the migrations folder (because knex needs to loop through the directory to find the files), and once inside app.js (because I can't make webpack treat them as external) Signed-off-by: Pablo Carranza Velez <pablo@resin.io> 2017-11-29 21:32:57 +00:00			`// Only used to be able to run "knex migrate:make <migration name>" on the development machine.`
