Juttle SQL Adapter

Code from the /lib and /test directory shared among PostgreSQL, MySQL and SQLite adapters.

List of optimized operations

• any filter expression read sql (note: read sql | filter ... is not optimized)
• head or tail
• reduce count(), sum(), min(), max(), sum(), avg(), count_unique()
• reduce by fieldname
• reduce -every :interval:

In case of unexpected behavior with optimized reads, add -optimize false option to read sql to disable optimizations, and kindly report the problem as a GitHub issue.
