feat(sql): Add history tables for static credentials

This adds history tables for `credential_static_store`,
`credential_static_json_credential`,
`credential_static_username_password_credential`, and
`credential_static_ssh_private_key_credential`. This also adds a base
table for the static credential history tables.
