Created Unassigned: Create Project Server Web Instance on Custom Web Application [22096]

We are no using the "Portal" web application to host Project server instances.

The script defaults to creating the project server web instances on the web application using the "Portal" type.

I modified the Config XML file and Installerfunction powershell file as follows to achieve this:

Config.XML - added two new keys: WebAPP and WebAppPort

```
<ProjectServer Install="true" ConfigFile="config-ProjectServer2013.xml" PIDKeyProjectServer="TBD">
<ServiceApp Provision="ServerName" Name="Project Server Service Application" ProxyName="Project Server Service Application" ManagedPath="PWA" ServiceAccount="Domain\account" ServiceAccountPassword="TBD
WebApp="https://foo.com" WebAppPort="" >
```

Modified the InstallerFucntion file

```

$projectManagedPath = $xmlinput.Configuration.ProjectServer.ServiceApp.ManagedPath
$projectWebApp = $xmlinput.Configuration.ProjectServer.ServiceApp.WebApp #this is news
