Introduce separate envvars for SMTP host & port instead of SMTP_ADDRESS

[tormi]

Let's introduce separate envvars for SMTP host & port instead of SMTP_ADDRESS:

charts/drupal/tests/drupal_deployment_test.yaml

Line 89 in c3b3a3b

value: RELEASE-NAME-mailhog:1025

Consider this scenario:

/**
 * Default SMTP settings.
 *
 * Mailhog address in Silta SMTP_ADDRESS env-variable is
 * in form 'hostname:port'. We need them separately.
 */
if (getenv('SILTA_CLUSTER')) {
  $smtp_address_parts = explode(':', getenv('SMTP_ADDRESS'));
  if (!empty($smtp_address_parts[0]) && !empty($smtp_address_parts[1])) {
    $config['smtp.settings']['smtp_host'] = $smtp_address_parts[0];
    $config['smtp.settings']['smtp_port'] = $smtp_address_parts[1];
  }
}
