accel-config: Add user_default_profile.conf

Add contrib/configs/user_default_profile.conf as a user default
configuration template.

It specifies one DSA and one IAX with all WQs and engines in one group
in each device.

Run "accel-config config-user-default -c user_default_profile.conf"
to apply the attributes to all available WQs and engines in each
device.

User can modify the attributes and/or remove a device per their
requirements.
