Renew the self-signed cert used by the API

[drago-draganov]

The setup always reuses the existing API cert (including self-signed cert).

With cert expiration of 1 year it's easy to hit the limit.
As minimum the setup should renew API's self-signed certificate if the current is close to expire (< 2-3 months.)

Replacing the IIS Administration API certificate if it has less than 3 months left sounds like the best approach.

The installer should log that the certificate is being replaced. We can do this by adding a verbose log entry to the PowerShell installation script.

The solution to this issue was creating a new certificate rather than deleting the existing Microsoft IIS Administration Server Certificate

If the server already has a Microsoft IIS Administration Server Certificate then a new certificate will be created with the format Microsoft IIS Administration Server Certificate {YEAR}
