Rework the tomoconfig default chains

This PR is intent to solve timeout on slow scans with some Lima detectors.

This fix have to be applied by configuration in each beamlines and detectors.

• tomoconfig can be setup with 2 new chain settings:
  • default_slow_single_chain and default_slow_accumulation_chain
  • This chains are only used for slow runners: return_ref, mesh and tiling for now
  • If a detector is not defined in this chains, the default one are anyway used
• Runners was reworked to property setup and cleanup DEFAULT_CHAIN
