WHAT

Implements a state machine for EDR renewal. Once an EDR is first negotiated the state machine will boostrap the
cached entry with a Negotiated state.

The state machine is composed by the following states:

  • Negotiated the primordial state. The EDR has been negotiated with the provided and stored in the EDR store
  • Refreshing the EDR is about to expire and another transfer process has been started for negotiating another EDR token with the same parameters
  • Expired: Once a new EDR is negotiated the old one is marked as Expired waiting for deletion
  • Deleting: Once the the retention period is expired EDR are marked as deleting

The EDR cached entry gets deleted by picking from the state machine the one that are in Deleting state.

WHY

User experience. Once the first Negotiate EDR request has been fulfill the EDR extension will ensure to renew automatically the EDR token before it expires.

FURTHER NOTES

Also in this PR the E2E test based on PostgreSQL has been moved to testcontainers. When wi will upgrade to EDC > 0.1.3
we could also leverage to the refactored PostgresqlStoreSetupExtension that uses testcontainers as well for testing the EDR storage.

Also in this PR for supporting testcontainers I've created a TxPostgresqlLocalInstance copy of the upstream one. It's mark for removal once we upgrade to the next EDC version.

Closes #600
