.Synopsis
   iDRAC cmdlet using Redfish API with OEM extension to launch iDRAC HTML KVM session using your default browser..
.DESCRIPTION
   iDRAC Cmdlet using Redfish API with OEM extension to to launch iDRAC HTML KVM session using your default browser.
 
   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) NOTE: For only this cmdlet, you still need to pass in idrac_username agrument. This is needed to create the temp URI to launch KVM session.
    
.EXAMPLE
   Invoke-IdracRemoteKvmHtmlSessionREDFISH -idrac_ip 192.168.0.120
   This example will first prompt for iDRAC username and password using Get-Credentials, then launch iDRAC KVM session using your default browser.
.EXAMPLE
   Invoke-IdracRemoteKvmHtmlSessionREDFISH -idrac_ip 192.168.0.120 -x_auth_token 7bd9bb9a8727ec366a9cef5bc83b2708 -idrac_username root
   This example using iDRAC X-auth token session will launch iDRAC KVM session using your default browser.
