SPFarm: Add SPServerCertificatePipeBind Support for the Central Administration with SPSE

Problem description

SharePoint Subscrioption Edition added a few Parameters for the SPCentralAdministration Commands. The Parameter -Certificate is one of them. In conjunction with the Parameter HostHeader, UseServerNameIndication, AllowLegacyEncryption and Url it is now possible to create a Central Administration with an Certificate Binding and a URL of your choosing.
Also with the benefit, that a .Provision() on the Webapplication or a psconfig run does not revert the URL to the default or removes the Binding from IIS.
Also you could run two or more instances of the Central Administration behind a Loadbalancer

Currently this is not possible with the SPFarm Ressource.

Suggested solution

In order to achieve this the following Steps would be required:

• Test if the Cerfificate is imported before running the New-SPCentralAdministration or Set-SPCentralAdministration Command and Import it if necessary
• Expand the Parameters for the SPCentralAdministration Commands
• Expand the Ressource with the Addional Parameters

I'd be happy to work on a pull request.
I'm a bit concerend that this might get in conflict with the existing SPCertificate Ressource, but also could reuse the existing code :)
Also I'm happy about feedback and if this enhanced fits in.

Start by locating the SPFarm resource and its handling of New-SPCentralAdministration and Set-SPCentralAdministration, then review the existing SPCertificate resource for reusable certificate-import behavior. Add support for SPServerCertificatePipeBind and the Certificate, HostHeader, UseServerNameIndication, AllowLegacyEncryption, and Url parameters, with tests covering certificate binding and the resulting Central Administration configuration.
