Add a switch to postpone pack jobs

[mafoipsl]

To test a new simulation, we begin with a 1 year (or more 3 years in the test) simulation. Is it possible to add a switch to postpone pack jobs until next PackFrequency?

In this example with CumulPeriod=3 we don't want to launch pack jobs. We want to wait until CumulPeriod=10.

--Debug1--> IGCM_post_Configure

--------Debug2--> IGCM_post_ModuloRuntimeFrequency : Master=10Y Slave=1Y CumulPeriod=3
--Debug1--> PackFrequency flag value : true

--------Debug2--> IGCM_post_ModuloRuntimeFrequency : Master=10Y Slave=1Y CumulPeriod=3
--Debug1--> TimeSeriesFrequency flag value : true

--------Debug2--> IGCM_post_ModuloRuntimeFrequency : Master=10Y Slave=1Y CumulPeriod=3
--Debug1--> SeasonalFrequency flag value : false-------Debug2--> POST-TREATEMENT flag value : true

If not possible, we have to delete the beginning of a simulation to keep a simulation based on a unique PackFrequency ie 10Y for instance.
