chore: User improvements (#3034)

## Changes
- Added basic DiffSuppression/Validations for user parameters that are
string enums.
- Added basic flow for display_name | login_name fields (should I create
a ticket and include its number for the 2nd step? incorrect values after
rename).
- Added integration test that shows which fields are visible when
querying a given user with different query commands.
- Added HasMfa to describe and added new asserts in users acceptance
test to show it's there and it's getting mapped (the only way to get it
`true` is to set MFA manually so I can only assert it's `false`).

## Doing right now
- Testing manually default_namespace / default_role

 #### *(breaking change)* refactored snowflake_users datasource
+> **IMPORTANT NOTE:** when querying users you don't have permissions to, the querying options are limited. 
+You won't get almost any field in `show_output` (only empty or default values), the DESCRIBE command cannot be called, so you have to set `with_describe = false`. 
+Only `parameters` output is not affected by the lack of privileges.

 Changes:
 - account checking logic was entirely removed
 - `pattern` renamed to `like`
