Make the slot_number field optional

[hug-dev]

The PKCS 11 provider can use the get_all_slots function to use the first slot returned if the slot_number field was not given. It will save some trouble to the admin!

What was the difference between that one and get_slots_with_token?

[hug-dev]

oh yeah I think get_slots_with_token should be used.
From the documentation:

tokenPresent indicates whether the list obtained includes only those slots with a token present

I am not fully sure of the difference between a slot and a token but I think a token is in a slot when there is actually something to use there.

Hi @hug-dev, if you want I can work on it.
Thank you

[hug-dev]

Indeed. My understanding is that slot = smartcard reader, token = smartcard in the reader. For general use get_slots_with_token is better. get_all_slots is useful only when learning about the actual readers (they have some metadata associated too).
