feat: .htaccess auto reload

[ntorga]

OpenLiteSpeed only read .htaccess on reload, thus we need to monitor for changes on .htaccess and reload OLS.

• A 2 to 3 minutes tick on Go to run a infra for checking if any .htaccess has changed on /app/html directory;
• Recommend using find with mtime to check for the modified files and -name for the name filtering, maybe 7 for depth is ok;
• Reload OLS once any modified file was found;
• After finishing the feature, recommend checking if .htaccess is being reload after OLS reload by putting a deny all on some .htaccess file and checking with curl if you get a 403 for example.

The same watchdog implementation used for SSL validation and replacement was applied to create the .htaccess watchdog.
