cmor_tables: updated ice sheet variables | MPI-ESM mPISM: updated cdocmorinfo regarding vertical axis and nominal resolution

- psimtest: added ncatted for source files (grid mapping attributes)
- aggregation headers: jsbach fixed settaxis command
- headers: added echo of cdo commands
- runpp: new cdo cmor version
- tables: pism update
- model specific cdocmorinfo: added absolute paths to gridfiles
- worked over conf dreq configuration files

Added helper scripts to treat cmorized data: check for missing files, additional files, alter/add version dirs, ncrcat, stats of CMORizing processes (used node hours) ...

Adding further experiments, variables and models to CMOR-tables,CV,scripts

See merge request !1

- adding CH4 variables (of TK)
- adding further variables (of MK)
- adding ice sheet variables (of CS)
- adding Ocean BGC variables (of BL)
- adding methane transient deglaciation and future experiments + MPI-ESM scripts
- adding test scripts and mapping for AWI-ESM

CMOR-tables: added few yet missing variables; Readme: updated with information about CV changes and variable mapping

- ncatted: added correction of several more attributes
- cdocmorinfo: updated source and Conventions attributes, fixed RIPF indices
- cmor-tables: updated cmor_version and Conventions attributes
- CV: added solidLand model component

CV/cmor: experiment_id replaced underscore with hyphen; runpp/aggr fixed problem with parent experiments

- fixed sftlf_dec dimension definition
mpiesm mapping/scripts:
- orog -> calculating out of geosp (echam var129) instead of using the topography input file
- frivera -> converting units to kg m-2 s-1
