Convert datetime in Lua within OffsetDateTime in Java

[valery1707]

Since datetime in Lua supports working with offsets, it is logical to allow it to be converted to OffsetDateTime in Java to expand the possibilities of working with dates

I haven't forgotten about:

• Tests
• Changelog - do I need to add something into Changelog?
• Documentation
• Commit messages comply with the guideline
• Cleanup the code for review. See checklist

@valery1707 You are right that OffsetDateTime is valid for Tarantool. ZonedDateTime also valid for this.

I'll check your implementation later.

Also, check the CI cause it's red now
