Symptom (bug) / Objective (enhancement)

Unattended install process does not support TLS connections to MySQL.

Reproduction procedure (bug)

1. On iTop 3.2.0-2 (not related to version)
2. With PHP 8.3.12 (not related to version)
3. MySQL instance configured with require_secure_transport=ON
4. Setup MySQL connections with TLS (config db_tls.enabled and db_tls.ca)
5. Then launch the setup/unattended-install/unattended-install.php script
6. Finally, see that the TLS connection to MySQL cannot be established:

Fatal error: Uncaught mysqli_sql_exception: Connections using insecure transport are prohibited while --require_secure_transport=ON. in /var/www/html/setup/unattended-install/unattended-install.php:313

Cause (bug)

TLS connection not implemented in the unattended install script:

iTop/setup/unattended-install/unattended-install.php

Lines 220 to 221 in ea5473a

	$oMysqli = new mysqli($sDBServer, $sDBUser, $sDBPwd);
	if ($oMysqli->connect_errno)

and

iTop/setup/unattended-install/unattended-install.php

Lines 313 to 314 in ea5473a

	$oMysqli = new mysqli($sDBServer, $sDBUser, $sDBPwd);
	if (!$oMysqli->connect_errno)

Proposed solution (bug and enhancement)

Add support for TLS connection based on this code in the docs and existing MySQL connection code in the app:

iTop/core/cmdbsource.class.inc.php

Lines 174 to 186 in ea5473a

	$oMysqli = new mysqli();
	if ($bTlsEnabled)
	{
	$iFlags = (empty($sTlsCa))
	? MYSQLI_CLIENT_SSL_DONT_VERIFY_SERVER_CERT
	: MYSQLI_CLIENT_SSL;
	$sTlsCert = null; // not implemented
	$sTlsCaPath = null; // not implemented
	$sTlsCipher = null; // not implemented
	$oMysqli->ssl_set($bTlsEnabled, $sTlsCert, $sTlsCa, $sTlsCaPath, $sTlsCipher);
	}
	$oMysqli->real_connect($sServer, $sUser, $sPwd, '', $iPort, ini_get("mysqli.default_socket"), $iFlags);

Disclaimer: PHP is not my language, sorry if something is broken or strange! Just let me know and I'll fix it.

Checklist before requesting a review

• I have performed a self-review of my code
• I have tested all changes I made on an iTop instance
• I have added a unit test, otherwise I have explained why I couldn't
• Is the PR clear and detailed enough so anyone can understand digging in the code?
