Unify terms and UI between 1Password lookups and facts module (#45427)

Browse source 
* Unify login behavior between 1Password lookup plugins and module

- Use the same names for all credential aspects
- Only require the minimal amount of information for each
- Add more examples

* Change parameter terms

- use terms in line with 1Password documentation.
- update examples
- update tests

* Improve error messages in lookup plugin

* Unify onepassword_facts with lookup plugins

- use same methods and logic for signing in or reusing existing session
- unify terms with lookup plugins

* Change rc test for determing login

An rc other than 1 can be returned when a current login session does not exist.

* Create AnsibleModuleError class

ansible.errors is not available to modules, so create an AnsibleModuleError class within the module

Do not user os.path.expanduser since this is already done by virtue of the type being "path" in the argument spec.

* Add note about risk with fact caching sensitive data

* Add note on op version that was used for testing

- C(op) 1Password command line utility. See U(https://support.1password.com/command-line/)
notes:
- "Based on the C(onepassword) lookup plugin by Scott Buchanan <sbuchanan@ri.pn>."
short_description: Fetch facts from 1Password items
- This module stores potentially sensitive data from 1Password as Ansible facts.
Facts are subject to caching if enabled, which means this data could be stored in clear text
on disk or in a database.
- Tested with C(op) version 0.5.3
short_description: Gather items from 1Password and set them as facts
description:
- M(onepassword_facts) wraps the C(op) command line utility to fetch data about one or more 1password items and return as Ansible facts.
- M(onepassword_facts) wraps the C(op) command line utility to fetch data about one or more 1Password items and return as Ansible facts.
- A fatal error occurs if any of the items being searched for can not be found.
- Recommend using with the C(no_log) option to avoid logging the values of the secrets being retrieved.
