FFDC Initial OpenBMC base URI variable
FFDC Initial OpenBMC base URI variable

The new OpenBMC URI would start with /xyz/openbmc_project ahead.
This means all our existing tests and library would be impacted.

To make the transition easier from existing /org/openbmc to newer
/xyz/openbmc_project a new variable is introduced in resource.txt

Use robot method to import variables from the resource.txt file,
in this case ${OPENBMC_BASE_URI}.
