Change open(file) to with block

Currently script which loads metadata definitions to database
uses open(file) to stream files. This isn't the best practice
because in case of any errors this code may not be safe.
To solve this problem this patch changes open(file) to
'with open(file) as...:' block. It allows us to ensure that every
resource is cleaned up when the code finishes running.
