PDO plugin: Reflections

* com.noccy.pdo: Implemented reflection for PDO databases, tables and columns. Reflectors for MySQL and Sqlite. * com.noccy.pdo: Added pdo:inspect command. * com.noccy.docker: Added basic stack management and commands. * com.noccy.docker: Moved commands to dedicated namespace. * Environment: readConfig and writeConfig helper added, with a flag to use the global config dir ~/.config/spark.
