StartTime and EndTime should be expressed as a UNIX timestamp

[enolfc]

Description

StarTime and EndTime (potentially others) fields of the VM usage record should be expressed as UNIX timestamp, otherwise APEL rejects the records.

This is what's shown in the APEL logs:

2023-05-22 05:20:29,315 - loader - WARNING - Message rejected. Parsing unsuccessful: Unknown datetime format!: 2023-05-21 23:11:40

Versions

This affects caso 4.x and newer

@enolfc probably this is also true in measure_time (https://github.com/IFCA/caso/blob/master/caso/record.py#L167) and in measure_time and start_time in (https://github.com/IFCA/caso/blob/master/caso/record.py#L290). We are working separatedly here https://github.com/IFCA/caso/tree/fix/115

yes, according to this: https://docs.egi.eu/users/getting-started/architecture/#public-ip-usage-record

and start_time in (https://github.com/IFCA/caso/blob/master/caso/record.py#L290).

The StAR contains this:

The format of the record is XML, using QNames. The currently defined name space is http://euemi.eu/namespaces/2011/02/storagerecord, denoted as “sr” in this document. All time and duration formats are ISO types

So I expect this not to be converted
