dev/core#1926 - Try to autodetect mysql ssl settings from the CMS config

[demeritcowboy]

Overview

This goes along with #18107 but isn't required by it. It just tries to autodetect if ssl is already used for mysql on the CMS side and prefill the parameters for use with civicrm-setup. This PR does require #18107 if you want to r-run the whole process, but you can sanity check this one on its own without running the whole process by:

1. Configure mysql for ssl.
2. Edit drupal settings.php to add a pdo section as per installation docs or as in dev/core#1926 - Allow SSL mysql connections for civicrm-setup #18107.
   • Note that even if you're not running the full install, there's a drupal bootstrap that will make it attempt to connect to the drupal database, so if the pdo params you're using aren't compatible with the real mysql ssl setup it will fail.
3. Run this debugging command cv core:install --debug-model --cms-base-url=http://site/ and look at the output. In the simplest case with no client certificate and no server verification but wanting ssl it will look something like:

   "db": {
        "server": "localhost:3306",
        "username": "drupal",
        "password": "pass",
        "database": "civi",
        "ssl_params": {
            "ssl": 1
        }
    },
    "cmsDb": {
        "server": "localhost:3306",
        "username": "drupal",
        "password": "pass",
        "database": "drup",
        "ssl_params": {
            "ssl": 1
        }
    },

Before

• Need to pass in the --db parameter for cv core:install to specify ssl settings.
• Manually need to update CIVICRM_UF_DSN in civicrm.settings.php after install.

After

• If the CMS config is using ssl for mysql then it should autodetect the ssl config for the --db parameter. You can still specify it manually if it guesses wrong.
• CIVICRM_UF_DSN in civicrm.settings.php automatically updated after install.

Technical Details

Autodetect is only for drupalish sites at the moment (drupal 7/8, backdrop).
