[Feature][RASTER] Generate band name with NetCDF EXTRA_DIM funded by
Ifremer

The NetCDF provided extra dimensional information. This information provides metadata on each band. These metadat can be used to explain the name of each band.

For example, the bands of a NetCDF file represents the temperature at a given depth. For the user, it is easier to select a band with depth information, rather than the number.

If the GDAL version is equal or greater than 1.10.0, the band name is
generated with the extra_dim information.
change output of QgsGdalProvider::generateBandName() and fix indentation
