Run with Postgres

[jakubdyszkiewicz]

Created new Makefile tasks

• start/postgres - start postgres with initialized DB
• run/standalone/postgres - runs CP with standalone postgres mode

moved test/postgres/docker-compose.yaml to tools/postgres/docker-compose.yaml, because it's now used in integration as well as in start/postgres.

Installation script is in install/postgres/resource.sql and is used in docker-compose.

Removed PluginConfig as it was ignored in 5 cases. Postgres is the first case in which we configure plugin, but it's kind of more convenient to retrieve it from PluginContext without type casting.

Is there any connect timeout to Postgres ?

Apparently, there is a problem with connectivity to Postgres on my machine and Control Plane stuck at start up:

KONVOY_GRPC_PORT=5678 \
	KONVOY_HTTP_PORT=5679 \
	KONVOY_ENVIRONMENT=standalone \
	KONVOY_STORE_TYPE=postgres \
	KONVOY_STORE_POSTGRES_HOST=localhost \
	KONVOY_STORE_POSTGRES_PORT=15432 \
	KONVOY_STORE_POSTGRES_USER=konvoy \
	KONVOY_STORE_POSTGRES_PASSWORD=konvoy \
	KONVOY_STORE_POSTGRES_DB_NAME=konvoy \
	go run ./app/konvoy-cp/main.go run

Rebased to master.
Renamed standalone to universal.
Added connection timeout - good point there! I tested with simple nc -l 15432 and it works. It was indeed stuck before.
Restored PluginConfig as discussed on Slack. Although we don't use it almost at all now, this might be useful when plugging in multiple sources of the same type.
