.PARAMETER deploymentPath
    The path to where the Sitecore instance was deployed. This is the path up the Website or similar
.PARAMETER hostNames
    The hostNames to replace for the site definitions. This is a key pair array in the form @{"localhostname"="site.com"; "othersitelocal"="othersite.com"}.
    Set it empty is you want to skip altering hostname attribute for site definitions in CD instances of Sitecore. 
    The site definitions should be in \App_Config\Include\Context\Website.config
.PARAMETER targetHostNames
    Same as hostNames but for targetHostNames. 
.PARAMETER webroot
    The additional and optional name for the webroot for the instance. Default is Website
