Integrate `Alembic` into `Ape` for the cache system

[johnson2427]

Elevator pitch:

Currently can init and purge a database, but need the ability to migrate the database when the ApeWorX team approves changes to the database structure.

Value:

Allows users to not have to purge and completely rebuild a database. They can migrate, keep all of their data, and continue to add to the sqlite database seamlessly.

Dependencies:

Alembic

Design approach:

Add alembic folder under the src folder, and set up the migration tool like we have in FastAPI applications in the past

Task list:

• [ ] Add alembic
• [ ] write out md file for how to use

Estimated completion date: 9/1/22

Design review:

Do not signoff unless:

• 1. agreed the tasks and design approach will achieve acceptance, and
• 2. the work can be completed by one person within the SLA. Design reviewers should consider simpler approaches to achieve goals.
