Add support for getting status

[jmgilman]

The way the module currently handles a locked vault is by throwing an error. There doesn't appear to be a way to check beforehand if vault data can be accessed - this makes conditional access difficult. My current workaround is a bit tedious:

- block:
    - set_fact:
        status: "{{ lookup('bitwarden') }}"
        unlocked: true
  rescue:
    - set_fact:
        unlocked: false
- block:
    - set_fact:
        home: "{{ lookup('env','HOME') }}"
        key: "{{ lookup('bitwarden', item, field='item') }}"
    - name: SSH directory exists
      ansible.builtin.file:
        path: "{{ home }}/.ssh"
        state: directory
        mode: 0700
    - debug:
        msg: "{{ lookup('bitwarden', item,  itemid=key.id, attachments=true, output=home+'/.ssh/'+item ) }}"
    - debug:
        msg: "{{ lookup('bitwarden', item+'.pub',  itemid=key.id, attachments=true, output=home+'/.ssh/'+item+'.pub' ) }}"
  when: unlocked

Basically, I use blocks to catch the error thrown when the vault is locked and set unlocked accordingly to conditionally run steps that require the vault to be unlocked. It would be nice to have a dedicated lookup parameter to fetch vault status to avoid resorting to this hacky approach.
