.Synopsis
   iDRAC cmdlet using Redfish API with OEM extension to export all server hardware information to a file locally using default browser session.
.DESCRIPTION
   iDRAC cmdlet using Redfish API with OEM extension to export all server hardware information to a file locally. You will be prompted to download the exported HW inventory using your default browser session. If you select yes, it will automatically launch a browser session and download the file. You may be prompted to enter iDRAC credentials if this is the first time you are using browser to access the iDRAC.
 
   Supported parameters to pass in for cmdlet:
    
   - idrac_ip: Pass in iDRAC IP
   - idrac_username: Pass in iDRAC username
   - idrac_password: Pass in iDRAC password
   - x_auth_token: Pass in iDRAC X-Auth token session to execute cmdlet instead of username / password (recommended)
    
.EXAMPLE
   Invoke-ExportHwInventoryLocalREDFISH -idrac_ip 192.168.0.120 -idrac_username root -idrac_password calvin
   # This example will export the complete server hardware information to a local file using your default browser session.
.EXAMPLE
   Invoke-ExportHwInventoryLocalREDFISH -idrac_ip 192.168.0.120
   # This example will first prompt for iDRAC username/password using Get-Credential, then export the complete server hardware information to a local file using your default browser session.
.EXAMPLE
   Invoke-ExportHwInventoryLocalREDFISH -idrac_ip 192.168.0.120 -x_auth_token 7bd9bb9a8727ec366a9cef5bc83b2708
   # This example using iDRAC X-auth token session will export the complete server hardware information to a local file using your default browser session.
