*Part 2 - introduce string type keys*

Why do we need support for String type primary keys?
Because
* generating a String type key is much faster than calculate the incremental
next decimal value
* Stateless, it can be generated on the fly
* already known before the entity is saved
* globally unique: different entities and distributed systems, hosts/tenants
could not produce exactly the same value
* sense of security since the malicious users can't guess the ID
* we advise to use nanoId, because it is tiny, secure, URL-friendly,
cryptographically strong, has no mandatory dependencies, 60% faster than UUID
and we can control the behaviour of alphabets to be used
* disadvantages:
*
** not naturally sortable according to creation time - for that we introduced
{{created_on_utc}} with nanoseconds
*
** less user readable - suggest to have a user friendly name instead the
primary key
What has changed?
part 1:
* {{AbstractPersistableCustom}} interface generic type id: T extends
Serializable - instead of Long
this change effects all entity codes but transparent for the users
part 2:
* general APIs like command, datatables, journal entries and notes are now
working with Serializable keys (not only Long)
* general services of command, datatables, journal entries and notes were
extended to handle Serializable keys
* enum type response data EnumOptionData is also generic and has a special
{{StringEnumOptionData}}
* model extensions, new columns to store string type ids:
*
** {{{}m_portfolio_command_source{}}}.{{{}resource_identifier{}}}
{{varchar(100)}}
*
** {{acc_product_mapping.product_identifier}} {{char(21)}}
*
** {{{}m_note{}}}.{{{}entity_identifier{}}} {{varchar(40)}}
* dependency of {{com.aventrix.jnanoid:jnanoid:2.0.0}}
