refactor(rollupconfig): update external package to avoid big bundle. …

…Remove unecessary rollup plugin Add databases packages as external instead of pack them into bundle. Add banner in dev env about package version. Remove rollup-plugin-re and rollup-plugin-json that are no longer needed. This package target only a backend usage, so esm module is just keep to test/future node esm usage. BREAKING CHANGE: Database are no longer packaged with bundle
