feat(datastore): Add DataBase Name Provider as optional parameter on DataStore plugin initializer

[baldarama]

Issue #

Description

this changes will allow developers to specify a name for the DataStore database file, this is needed in apps that allow multiple users one at at time.

app is configured with a sync expression that syncs all records of a user based in his "accountId"
each user has a unique "accountId"
the app can be used by multiple users one at a time

scenario
there are 2 users User a and User b

1. User a logs in
2. data store is synced
3. User a logs out
4. User b logs in
5. data store is synced

in the above scenario user b records will not be synced, only the changes that happened between the time user a logged out and user b logged in will be synced, user b may be able to see user a records.

solution 1 (this is not a good solution but it is what can be done before changes on this pr)
clear data store before sync when it is detected that a different user has logged in

solution 2 (only possible with the changes in this pr)
specify datastore database name in a way that each user has its own database file.
