Create an EAB token that is specific to a role's ACME directory. NOTE: Within Vault ACME there are different ACME directories which an EAB token is associated with;

1. Default directory (pki/acme/) - Do not specify a value for issuer nor role parameters.

2. Issuer specific (pki/issuer/:issuer_ref/acme/) - Specify a value for the issuer parameter

3. Role specific (pki/roles/:role/acme/) - Specify a value for the role parameter

4. Issuer and Role specific (pki/issuer/:issuer_ref/roles/:role/acme/) - Specify a value for both the issuer and role parameters
