Add data structures

For migrated web app, we need to more fields in cache e.g., IV and
is_migrated flag to handle it separately.

Because cipher algorithm, iv and key size could be different between old
secure storage, it depends on product implementation. So this
architecture needs more flexibility.

A lot of code changed because of the principle data structure is added
from the bottom.
