pkcs11-tool should provide an option to get slot information as pkcs11-uri about opensc HOT 1 CLOSED

The PKCS#11 URI identifies not only the slots, but also objects, so if we should have it, I would say it should be just printed in the output where we list slots or objects. It has also several non-mandatory parts, such as PIN, module path, which should probably not be used in the default print.

$ pkcs11-tool -L
Available slots:
Slot 0 (0x0): Yubico YubiKey OTP+CCID 00 00
  token label        : clevis
  token manufacturer : piv_II
  token model        : PKCS#15 emulated
  token flags        : login required, rng, token initialized, PIN initialized
  hardware version   : 0.0
  firmware version   : 0.0
  serial num         : 0123456789abcde
  pin min/max        : 4/8
  uri:               : pkcs11:model=PKCS%2315%20emulated;manufacturer=piv_II;serial=0123456789abcde;token=clevis 

The reason why it was not implemented so far is likely nobody needed that so far. Every time I needed a PKCS#11 URI in the output, I usually used p11tool from gnutls or p11-kit, which prints these.

So if you are (or anyone else) interested in implementing this, we would be happy to accept patches.
