Add a new util called `resolveAbsolutePath` to allow providing absolute
path for environment variable like `STORAGE_LOCAL_PATH`.
If the path in the env start with `/` we'll not prefix it with
`process.cwd()`.
Also we're using a static path for the old `db_initialized` file now
named `db_status` and stop using the env variable for this file as this
one shouldn't ne stored in the `STORAGE_LOCAL_PATH`.
