Quick fix to support date/time conversion to "ISO instant" format

[tdddblog]

Motivation

Before automatic conversion of date/time fields based on LDD definition is implemented, we need a way to specify a list of date / time fields to be converted to "ISO instant" format supported by Elasticsearch.

Additional Details

• Keep existing logic and convert all fields having "date" in their names.
• Provide an option to list field names that need to be converted to ISO format in Harvest configuration file.

Acceptance Criteria

Given an attribute in a label that is an ASCII_Date type from PDS4, but does NOT contain date in the attribute name
When I perform the configuration noted below, and ingest the data
Then I expect harvest to convert these attributes to ISO dates

Engineering Details

An example of new dateFields element in Harvest configuration file:

<autogenFields>
  <dateFields>
    <field>cassini:VIMS_Specific_Attributes/cassini:earth_received_start_time</field>
    <field>cassini:VIMS_Specific_Attributes/cassini:earth_received_stop_time</field>
    <field>cassini:VIMS_Specific_Attributes/cassini:start_time_doy</field>
    <field>cassini:VIMS_Specific_Attributes/cassini:stop_time_doy</field>
  </dateFields>
</autogenFields>

#54 will be a future, better solution at a later date.
