Dropwizard JDBC connection pool setting

[zloster]

Increase the timeout when waiting to obtain connection from a busy pool.

After implementing changes in the code to get non-repeating IDs and increasing the timeouts to the DB I've only fixed the Dropwizard with Hibernate and MySQL. The permutation with PostgreSQL/Hibernate and PostgreSQL/JDBI3 still are not passing the checks. I've tried to track down the problem but no luck currently.

What checks are needed:

• locally on higher concurrencies 32->64 the number of issued queries to the DB fails suddenly. So probably I have to check some settings for expirations/waiting for Jetty.
