PipelineCleanup_ResourceSearch.ps1

<#
This example helps look into resources that got created as a part of running OCI PS Modules examples and optionally allows some resources to be cleaned up.
This example also demonstrates the power of powershell pipelines https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_pipelines.
This example requires:
1) Modules OCI.PSModules.Database,OCI.PSModules.Resourcesearch,OCI.PSModule.Identity,OCI.PSModules.Core. Install the modules from Powershell Gallery.
