Support for ASP.NET apps deployment

This feature aims to add support for ASP.NET apps depolyment from GIT repository.
In order to do that the following changes should be made:
1. In Dashboard add new service type to services drop-down list and write a modal form for the wizard which is similar to IIS service form and differs only by additional field with GIT repository address
2. In murano-api and python- muranoclient add API for new service ("aspNetApps") similar to IIS API with additional attribute
3. In murano-conductor add rules for aspNetApps service which are similar to IIS rules with one additional steps to install app with GIT repository as a parameter
4. In murano-conductor host initialization script and config file add setting to specify IP of SMB file share where ASP.NET prerequisites are located
5. Write PowerShell script/ExecutionPlan that checks-out ASP.NET app sources from GIT repository, builds them (using downloaded tools from prerequisites) and copies built app to Inetpub folder

There is a lot of copy-paste in steps above. This will be eliminated when there would be a mechanisms for reusing services/inheritance
