make connection attemps more readable

[Despire]

closes #528

Example of the changes when the connection is unhealthy:

#initial start of the service

11:37AM INF internal/utils/log.go:37 > Using log with the level "debug" module=builder
11:37AM INF services/builder/builder.go:77 > Initiated connection Context-box: localhost:50055, waiting for connection to be in state: READY module=builder
11:37AM WRN services/builder/builder.go:124 > connection to Context-box is not READY module=builder
11:37AM DBG services/builder/builder.go:125 > connection to Context-box is IDLE, waiting for the service to be reachable module=builder
11:37AM WRN services/builder/builder.go:124 > connection to Context-box is not READY module=builder

# make contextbox fail again

11:38AM WRN services/builder/builder.go:124 > connection to Context-box is not READY module=builder
11:38AM DBG services/builder/builder.go:125 > connection to Context-box is IDLE, waiting for the service to be reachable module=builder
11:38AM WRN services/builder/builder.go:124 > connection to Context-box is not READY module=builder
