Populate publication year field based on dateOfPublication field

Purpose/Overview:
In order to eliminate the need for manual entry of same or similar data in multiple places, we need to populate publication year stored publicationPeriod.start  and publicationPeriod.end based on the data provided in the dateOfPublication data.

Assumptions:

• The method should not override the data that is already stored in the field in case the user decides to populate it with known data. 
• The examples below do not attempt to cover all possible values but are based on the data from the libraries that are live with FOLIO and should cover big part of existing cases.  If the value of dateOfPublication cannot be parsed, then publicatinPeriod fields should be left empty.

Requirements/Scope: 

1. Examples of instance.publication array that has one dateOfPublication element provided

*publicationPeriod.end must be after publicationPeriod.start

2. Examples of instance.publication array that has more than one dateOfPublication element provided:

*publicationPeriod.end must be after publicationPeriod.start 

Approach:
TBD by dev

Acceptance criteria:

• Publication year populated according to specs above
• All other values in dateOfPublication are ignored and Publication year is empty
• Migration scripts are provided
• The publication year is populated on create of the instance only if specific values are not already provided

Out of scope:

• Data import
• UI implementation
