[enhance] (auth) add option to disable login with empty pass

[iaorekhov-1980]

What problem does this PR solve?

This PR adds new configuration property ldap_allow_empty_pass to prohibit option for existing user to login into LDAP with empty password.
If ldap_allow_empty_pass in ldap.conf is not specified or specified as true - user can login with empty pass (existing behavior).
If ldap_allow_empty_pass specified as false - login attempt with empty password will be rejected with corresponding error message.

Could you please include this PR into 4.x and 3.1.x branches, please!

Issue Number: close #60353

Related PR: #xxx

Problem Summary:

Currently for existing user it is possible to login into LDAP with empty password.
New configuration property disables such option, but default behavior still allows to login without specified password.

Check List (For Author)

• Test

  • Regression test
  • Unit Test
  • Manual test (add detailed scripts or steps below)
  • No need to test or manual test. Explain why:
    • This is a refactor/code format and no logic has been changed.
    • Previous test can cover this change.
    • No code files have been changed.
    • Other reason

• Behavior changed:

  • No.
  • Yes.

1. ldap.conf and LdapConfig.java - new configuration ldap_allow_empty_pass property with default value true to keep existing behavior as default
2. ErrorCode.java - specific error message for case with empty password was added
3. LdapAuthenticator.java and Auth.java - additional check was added to validate two conditions
   3.1 user has specified empty password
   3.2 property ldap_allow_empty_pass is false and doesn't allow to login with empty password
   If both conditions met - authentication is failed and new error is returned.
4. LdapAuthenticatorTest.java - introduced new test method to validate existing behavior (without specified ldap_allow_empty_pass property or true) and new one (with ldap_use_ssl property specified to false) to check that login is still successful in first case and failed in the second one.

• Does this need documentation?
  • No.
  • Yes.
