[bitwarden] ability to fetch all fields from an item

[honzasterba]

Sometimes a projects has a lot of secrets (more than 10). And its cumbersome to write $(kama secrets fetch ...) with a lot of field names.

I want to be able to just fetch all the fields from a given item and then just use these with $(kamal extract NAME)

I think we can just allow the name to be passed without any fields and then return all the values - so something like this:

          elsif (item_fields = item_json.dig("fields"))
            item_fields.each do |item_field|
              results["#{item}/#{item_field["name"]}"] = item_field["value"]
            end
          else

Then we can avoid the special __ALL__ value and you can say:

SECRETS=$(kamal secrets fetch --adapter bitwarden --account email@example.com ITEM)
FIELD1=$(kamal secrets extract FIELD1)

this is in conflict with the current code which just defaults to extracting a password from the item selected
currently secrets fetch ITEM returns a hash {"ITEM" => "password from item"} for login item, otherwise an error
another idea I had was to add it as an arg option kamal secrets fetch --all-fields ITEM not sure how feasible that is as it would impact the overall adapter API
another idea is to do make secrets fetch ITEM return all the fields as { "FIELD_1" => val, ... } if the item is not a Login item, that would not break compatibility
WDYT?
