### Summary

While setting up sonarqube and automating setting the admin password directly in the database, I noticed that their bcrypt implementation is outdated and only supports the 2a version, while the password_hash bcrypt filter using passlib defaults to the latest version (2b).

I'd like to set the ident parameter of passlib bcrypt function from the password_hash filter (like with rounds).

Right now I'm doing this:
```yaml
    - name: encrypt password
      command:
        cmd: python3 -
        stdin: |
          from passlib.hash import bcrypt
          print(bcrypt.using(rounds=12,ident="2a").hash("{{ admin_password }}"))
      register: tmp
```
as a workaround.

Obviously, sonarqube should upgrade their bcrypt version, but ansible should also be able to handle this.

### Issue Type

Feature Idea

### Component Name

password_hash

### Additional Information

```yaml
password: "{{ admin_password | password_hash('bcrypt', rounds=12, ident='2a') }}"
```
