Could we provide selection of individual years, months, days rather than a range?

Description

C3S might want to allow picking of a list of years, months and days.

xarray can do this, very simply, e.g.:

>>> ds.tas.sel(time=[cftime.DatetimeGregorian(1986, 11, 16), cftime.DatetimeGregorian(1987, 3, 16, 12), cftime.DatetimeGregorian(1987, 9, 16)])  
<xarray.DataArray 'tas' (time: 3, lat: 256, lon: 512)>

At the moment, we do:

time=<start>/<end>

We will need something like:

year=<y1>,<y2>,<y3> &
month=<m1>,<m2>,<m3>

E.g.: if you want January and July for 2001,2003 and 2010

year=2001,2003,2010&month=01,07

Issues:

• user can select either time or year/month
• what about day and hour?
