ARGO-4893 Issue during excluding metric egi.cloud.openstack-vm from fedcloud SITES

[cthermolia-grnet]

We modified recomputations. Before calculating previous status
the dataset is passed from an CalcRecomputation operation that checks if the metric is in exclude period and changes it status
to exclude if yes.
Then the dataset wil be passed to the CalcPrevStatus operation where the previous status and timestamp are calculated.
With this way we simplify calculations .

//we test if for a period extending today all the today data has EXCLUDED status
// exclude period: "start_time": "2025-02-01T00:00:00Z" - "end_time": "2025-02-02T00:00:00Z",
//the exclude period extends today , so all expected data should have EXCLUDED status. note tha
//the first elements should keep it's previous status MISSING as no previous data exist in dataset

//we test if for a period extending today all the today data has EXCLUDED status and previous state is correctly
EXCLUDED as period extends today
//the initial dataset has also yesterday data to check if previous status is correctly calculated
