Please unify variable guid and the usage of variables in invite config

[Martin Vogel]

The setup_invite_config tasks already use a variable for the ldap guid called ldap_guid_field( and there is a ldaps port called ldap_ssl_port )

Unfortunately these variables aren't documented in the variables overview - why I defined ldap_map_guid variable in my PR ( #293 )

connections-automation/roles/third_party/ibm/tdi-install/vars/main.yml

Lines 70 to 71 in 97eb462

 __ldap_map_guid:                "{{ ldap_map_guid | default('entryUUID') }}" 
 __ldap_map_uid:                 "{{ ldap_map_uid | default('uid') }}" 

In my opinion here it needs some steps for a standardization:

• add var __ldap_ssl_port to vars

  __ldap_ssl_port: "{{ (ldap_ssl_port | default('636')) }}"

  and replace ldap_ssl_port | default('636') with __ldap_ssl_port

  connections-automation/roles/hcl/connections/post_install_config/tasks/setup_invite_config.yml

  Line 43 in 97eb462

   - { protocol: 'ldaps', prop: 'ssl_href', port: "{{ ldap_ssl_port  | default('636') }}" } 

• add var __ldap_map_guid to vars

  __ldap_map_guid: "{{ ldap_map_guid | default('entryUUID') }}"

  and replace ldap_guid_field | default('entryUUID') with __ldap_map_guid

  connections-automation/roles/hcl/connections/post_install_config/tasks/setup_invite_config.yml

  Line 55 in 97eb462

   - { prop: "{{ __selfreg_ldap_guid_xpath }}", value: "{{ ldap_guid_field  | default('entryUUID') }}" }

  Line 63 in 97eb462

   - "${ldap:{{ ldap_guid_field | default('entryUUID') }}}" 

• replace ldap_guid_field | default('entryUUID') with __ldap_map_guid

  Line 55 in 97eb462

• finally update missing vars in variable overview page

... and the variable ldap_ssl_port can be used in the issue " LDAP ports hardcoded #276 ", too.
