inherit testblock configuration

[floweisshardt]

for a large number of similar testblocks (>10-100) it's not very comfortable to configure every testblock individually in the testblockset.yaml files. Instead it would be nice to configure metrics for a master testblock and then use the same configuration in all other testblocks.

Questions:

• how to handle different groundtruth settings?

use something like https://github.com/mojin-robotics/mojin_robots/blob/kinetic-devel/mojin_hardware_config/robots/cob4/config/base_driver.yaml#L21-L25 to define common parts for a yaml
then use it like https://github.com/mojin-robotics/mojin_robots/blob/kinetic-devel/mojin_hardware_config/robots/cob4/config/base_driver.yaml#L34
set additional, different groundtruth like https://github.com/mojin-robotics/mojin_robots/blob/kinetic-devel/mojin_hardware_config/robots/cob4/config/base_driver.yaml#L35
