[19.0][MIG] auth_ldaps: Migration to 19.0

[BT-vstoev]

+ Functional change: Handling the "Test Connection button":

• The button "Test Connection" in Odoo v18-19 calls a method in core test_ldap_connection - https://github.com/odoo/odoo/blob/19.0/addons/auth_ldap/models/res_company_ldap.py#L266

• Inside the method a conf dict is constructed and then the _connect method is called directly with that dict.
• Because of this hardcoded dict the "Test Connection" fails for the auth_ldaps module as we introduce new fields that should be part of the configuration for it.
• I thought about some approaches on how to solve this:
  • full override of the test_ldap_connection method. This will work, but doesn't seem like a good practice.
  • use if conf.get("is_ssl") in the _connect method extension in auth_ldaps instead of the current if conf["is_ssl"]:. This will obviously make the button "work", but actually it will not be performing a proper test of an SSL connection.. so technically - not work :)
  • Add context to the button and based on the presence of this context enrich the configuration from the record - this is the approach I chose.
