     (check parameters 'JREDownloadUrl' and 'JREInstaller')
   - if 'UseLocalFiles' is set to true script will look in LocalStorage for 'JREInstaller' and 'SolrPackage'
   - install JRE
   - install Solr
   - create certificates for domain 'CertificateName'
   - setup SSL for Solr
   - install Solr as a Windows Service
