Add support for different storages #57
Description
This task can be completed after #49 #56
it is necessary to make it possible to store the connection in different repositories (locally, s3 - external storage and git repository - limit to private, yandex disk etc.)
it is also necessary to think over the mechanism by which the data will be encrypted correctly - to consider whether it is necessary to change the current logic of storing the master key.
You also need to think about synchronization.
when switching storages, will there be access to others, etc., and will it be handled correctly?
