.Synopsis
   iDRAC cmdlet using Redfish API to set, change or delete BIOS passwords (system or setup)
.DESCRIPTION
   iDRAC cmdlet using Redfish API to set, change or delete BIOS passwords (system or setup).
   - idrac_ip: Pass in idrac IP
   - idrac_username: Pass in idrac user name
   - idrac_password: Pass in idrac password
   - x_auth_token: Pass in iDRAC X-Auth token session to execute cmdlet instead of username / password (recommended)
   - password_type: Set, Change or Delete BIOS password, pass in the type of password you want to change. Supported values are: Sys or Setup. NOTE: Make sure to pass in exact string value as listed (case sensitive values)
   - old_password: Change BIOS password, pass in the old password. If you are setting new password, pass in '""' for value
   - new_password: Change BIOS password, pass in the new password. If you are clearing the password, pass in '""' for value
   - reboot_server: Pass in "y" to reboot the server now or "n" to not reboot the server. If you don't reboot the server now, job ID will still get scheduled and will execute on next server reboot.
.EXAMPLE
    Set-BiosChangePasswordREDFISH idrac_ip 192.168.0.120 -idrac_username root -idrac_password calvin -password_type Sys -old_password '""' -new_password p@ssw0rd
    This example shows setting BIOS system password
.EXAMPLE
    Set-BiosChangePasswordREDFISH idrac_ip 192.168.0.120 -password_type Sys -old_password '""' -new_password p@ssw0rd
    This example shows first prompting for iDRAC username/password using Get-Credentials, then set BIOS system password
.EXAMPLE
    Set-BiosChangePasswordREDFISH idrac_ip 192.168.0.120 -password_type Sys -old_password '""' -new_password p@ssw0rd -x_auth_token 7bd9bb9a8727ec366a9cef5bc83b2708 -reboot_server y
    This example shows rebooting the server now to set BIOS system password using iDRAC X-auth token session
.EXAMPLE
    Set-BiosChangePasswordREDFISH idrac_ip 192.168.0.120 -idrac_username root -idrac_password calvin -password_type Sys -old_password p@ssw0rd -new_password newPassW0rd -reboot_server y
    This example shows rebooting the server now to change BIOS system password
.EXAMPLE
    Set-BiosChangePasswordREDFISH -idrac_ip 192.168.0.120 -idrac_username root -idrac_password calvin -password_type Setup -old_password p@ssw0rd -new_password '""' -reboot_server n
    This example shows creating a job to delete BIOS setup password which will happen on next server manual reboot.
