Mint records with DataCite-like provider

[fenekku]

Confirmation is needed on this task:

Implement and integrate minters to generate internal record persistent identifiers (pid_type=recid). Rather than legacy record identifiers, random 10-character alphanumeric string (with checksum) should be used.

• [x] implement provider, minter and fetcher in invenio-pidstore: https://github.com/inveniosoftware/invenio-pidstore/pull/125
• [x] integrate in invenio-rdm-records fake records: https://github.com/inveniosoftware/invenio-rdm-records/pull/31

This is the task that will finally connect base32-lib functionality with record minting (via invenio-pidstore).

Did it in invenio-pidstore mostly.

@fenekku Shall we link each point's PR (So we only have issues in the board?) I beleive the first item is https://github.com/inveniosoftware/invenio-pidstore/pull/125, no?

Im slowly removing PRs from the board when linked to an issue.

[fenekku]

Yes, done.
