Description

Currently apple pay related details are being stored in the connector metadata, as in future we are going to add apple pay decrypted flow support for ios app we will be collecting the apple pay payment processing certificates as well. As this ppc and ppc key needs to be securely stored, we need to move the existing certificates to a new column which stores the encrypted certificates.

This pr adds a api end point (/apple_pay_certificates_migration) to migrate the apple pay details form the merchant connector account metadata to the newly added column connector (connector_wallets_details). This api takes list of merchant_ids as input and then lists all the configured merchant connector accounts for that merchant id. After which it checks for the apple pay details in the metadata in the merchant connector account, if present it is encrypted by merchant's DEK (Data Encryption Key) and will be stored in the newly added column (connector_wallets_details) in the merchant connector account. Response contains the list of merchant_ids for migration succeeded (migration_successful) and failed (migraiton_failed).

Additional Changes

• This PR modifies the API contract
• This PR modifies the database schema
• This PR modifies application configuration/environment variables
