Accessing the RMM via kiratool in the Intel PDK

A user name and password is required to access the Remote Mangement Module (RMM).
The user name and password are made avalable to the PDK by setting the following
2 environment variables:

'RMMuser' : the user name
'RMMpassword' : pawword

The hardware detect in the PDK uses the values of these 2 evironment variables
when accessing the RMM. If these environment variable are not set in the environment,
the default RMM user and password is used.
