user-jwts issues

[DamianEdwards]

• user-jwts create should print the JWT details after creation, always including the name & compact format, and any custom values that were passed
• user-jwts print should print the minimum JWT details including id, name, audiences, dates, custom roles/scopes/claims
• user-jwts print should be formatted as fields, not the raw JSON storage format
• user-jwts print seems to shows only a single audience for a token with multiple audiences
• user-jwts throws exceptions for unrecognized command line options
• user-jwts --name option should support an alias of -n
• user-jwts help text for --issuer option should quote the default value of "dotnet-user-jwts" and end with a period
• user-jwts help text for --scheme option should end with a period
• user-jwts help text for --role option should end with a period
• user-jwts help text for --claim option should end with a period
