Description Of Change

The issue is raised here

• Enabled skipLocked, forShare, lockOuterJoinFailure, lock properties for Oracle dialect.
• Oracle does not have shared locks on individual table rows, FOR UPDATE is what i found closest to
  forShare dialect support .
• FOR UPDATE cant be used in sql's along with these :
  • ORDER BY
  • FETCH NEXT 1 ROWS ( creates a inline view, ...)

It results in error
ORA-02014: cannot select FOR UPDATE from view with DISTINCT, GROUP BY, etc.

We can instead generate a subquery like this to avoid error , but it's not equivalent and is not correct all the time and might cause issues.
SELECT "id", "username", "awesome", "createdAt", "updatedAt" FROM "users" "user" WHERE rowid in (select rowid from "users" "user" where "user"."username" = 'jan' ORDER BY "user"."id" OFFSET 0 ROWS FETCH NEXT 1 ROWS ONLY) FOR UPDATE;

instead of

SELECT "id", "username", "awesome", "createdAt", "updatedAt" FROM "users" "user" WHERE "user"."username" = 'jan' ORDER BY "user"."id" OFFSET 0 ROWS FETCH NEXT 1 ROWS ONLY FOR UPDATE;

Modified tests to use different model API's just to simulate the locking functionality .
-- findOrCreate is replaced with findAll and create
-- findByPK instead of findByOne
