1.2.0 Boring as Batman

• Implemented improvements to dataset search and info cli outputs
• Can now specify a range of years to process to ingest cli (e.g. 2000-2005)
• Fixed metadata_type update cli not creating indexes (running system init will create missing ones)
• Enable indexing of datacube generated NetCDF files. Making it much easier to pull
  selected data into a private datacube index.
  Use by running datacube dataset add selected_netcdf.nc.
