Split the code to bin and lib
bin - use lib and start webserver
lib - whole pod business logic

Added connection pool, make it shareable across threads
Enabled WAL mode
Set sqlcipher encryption scheme to 4

Added trigger test as an showcase

Added webserverUrl property to PluginRun, to allow reaching the plugin
webservers in all supported configurations.
Reminder, current configurations POD and Plugins can run is:
POD on host, plugin in docker (using host networking)
POD in docker, plugin in docker (using custom user network)
POD in docker, plugin under kubernetes (using DNS to resolve plugin address)
fix trigger endpoint in test, use 8008 port for localhost plugins
