elasticsearch::user cannot remove users without a password (ensure => absent requires password)

[milad-zanganeh]

Attempting to remove an Elasticsearch user with Puppet using ensure => absent fails because the module requires a password parameter even for deletion.

Steps to Reproduce

1. Declare a user resource without a password and with absence:
   • Manifest:
     • elasticsearch::user { 'some.user': ensure => 'absent' }
   • Or Hiera:

     users::elasticsearch:
       some.user:
         ensure: absent

2. Apply the catalog.

Actual Result
Puppet errors with:

• Error 500: Evaluation Error: Elasticsearch::User[some.user]: expects a value for parameter 'password'

Expected Result

• Deleting a user with ensure => absent should not require a password.
• No password operations should be performed for absent resources.
