ktest: Add OVERRIDE keyword to DEFAULTS section

Browse source 
The OVERRIDE keyword will allow options defined in the given
DEFAULTS section to override options defined in previous DEFAULT
sections.

Normally, options will error if they were previous defined.
The OVERRIDE keyword allows options that have been previously
defined to be changed in the given section.

Note, the same option can not be defined in the same DEFAULT section
even if that section is marked as OVERRIDE.

# DEFAULTS OVERRIDE

# Options defined in the DEFAULTS section can not be duplicated
# even if they are defined in two different DEFAULT sections.
# This is done to catch mistakes where an option is added but

# The OVERRIDE keyword can be added to a section to allow this
# section to override other DEFAULT sections values that have
# been defined previously. It will only override options that

# can not be defined in the same section even if that section
# is marked OVERRIDE.

# Both TEST_START and DEFAULTS sections can also have the IF keyword
