Fix sonars in apex-pdp

Addressed the following issues:
- initialize mocks before use
- use parameterized queries
- Random() is not secure
- provide parameterized type for generics
- unused imports
- constructor visibility
- use compute() instead of containsKey()/put()
- make final fields static
- rename constants to all upper case
- no assert() in Thread.run() methods
- nested try
- nested if/else
- too many break/continue
- use try-with-resources
- repeatable annotations
- overlapping characters in reg ex
- hashcode is not sufficient in compareTo()
- need equals() with compareTo()
- make class an interface
- use parameterized test
- multiple calls in assert()
- log or re-throw
- use different type of lambda
- use parameterized logging
- use StringBuilder instead of concatenation
- use StandardCharsets.UTF_8
