function Restore-RubrikDatabase
{
  <#
      .SYNOPSIS
      Connects to Rubrik and restores a MSSQL database

      .DESCRIPTION
      The Restore-RubrikDatabase command will request a database restore from a Rubrik Cluster to a MSSQL instance. This
      is an inplace restore, meaning it will overwrite the existing asset.

      .EXAMPLE
      Restore-RubrikDatabase -id MssqlDatabase:::c5ecf3ef-248d-4bb2-8fe1-4d3c820a0e38 -targetInstanceId MssqlInstance:::0085b247-e718-4177-869f-e3ae1f7bb503 -FinishRecovery -maxDataStreams 4 -timestampMs 1492661627000
      
      Restore database to declared epoch ms timestamp.

      .EXAMPLE
      Restore-RubrikDatabase -id $db.id -recoveryDateTime (Get-Date (Get-RubrikDatabase $db).latestRecoveryPoint) -maxDataStreams 1 -FinishRecovery

      Restore the $db (where $db is the outoput of a Get-RubrikDatabase call) to the most recent recovery point for that database.
