DXCDT-601: Supporting multiple identifiers for blocks list and unblock commands

[willvedd]

🔧 Changes

Currently, the auth0 users blocks list and auth0 users blocks unblock commands only support user ID as the identifier. Additional identifiers were requested in #804. To address this request, this PR adds the support for email, username and phone number as identifiers for these commands in addition to the user ID.
