function Invoke-RubrikRESTCall {
<#
      .SYNOPSIS
      Provides generic interface to make Rubrik REST API calls
      
      .DESCRIPTION
      The Invoke-RubrikRESTCall allows users to make raw API endpoint calls to the Rubrik REST interface. The user
      will need to manage the format of both the endpoint call(including resource ids) and body, but provides the
      option to make cmdlet independent API calls for automating Rubrik actions through PowerShell. The Rubrik API
      reference is found on the Rubrik device at:
        <Rubrik IP>/docs/v1

      .EXAMPLE
      Invoke-RubrikRESTCall -Endpoint 'vmware/vm' -Method GET

      Retrieve the raw output for all VMWare VMs being managed by the Rubrik device.

      .EXAMPLE
      Invoke-RubrikRESTCall -Endpoint 'vmware/vm' -Method GET -Query (New-Object -TypeName PSObject -Property @{'name'='msf-sql2016'})

      Retrieve the raw output for the VMWare VM msf-sql2016 using a query parameter.

      .EXAMPLE
      $body = New-Object -TypeName PSObject -Property @{'slaID'='INHERIT';'ForceFullSnapshot'='FALSE'}
      Invoke-RubrikRESTCall -Endpoint 'vmware/vm/VirtualMachine:::fbcb1f51-9520-4227-a68c-6fe145982f48-vm-649/snapshot' -Method POST -Body $body
      
      Execute an on-demand snapshot for the VMWare VM where the id is part of the endpoint.
