<#
    .SYNOPSIS
        Configures a Refrenced or Managed Geo Database
    .PARAMETER Ensure
        Indicates if the GeoDatabase should be configured or not. Take the values Present or Absent.
        - "Present" ensures that GeoDatabase is Configured with a server whether as a refrenced or Managed one.
        - "Absent" ensures that GeoDatabase is Un-Configured i.e. when present (Not Implemented).
    .PARAMETER DatabaseServer
        Host Name of the Machine on which the GeoDatabase is installed and Configured.
    .PARAMETER DatabaseName
        Name of the GeoDatabase
    .PARAMETER ServerSiteAdministrator
         A MSFT_Credential Object - Primary site administrator of the Server to register the GeoDatabase.
    .PARAMETER DatabaseServerAdministrator
        A MSFT_Credential Object - Database Admin User
    .PARAMETER SDEUser
        A MSFT_Credential Object - A SDE User
    .PARAMETER DatabaseUser
        A MSFT_Credential Object - A Geo-Database User
    .PARAMETER IsManaged
         Boolean to Indicate if the GeoDatabase is Managed.
    .PARAMETER EnableGeodatabase
        Boolean parameter to Indicate Enabling of a Geo-Database.
    .PARAMETER DatabaseType
        Type of Database Product used to install the GeoDatabase - "AzureSQLDatabase","SQLServerDatabase","AzurePostgreSQLDatabase","AzureMISQLDatabase"
