Make Hardware lifetime for EKS dynamic

[geurjas]

The docker image has hardcoded 5 years lifetime duration:
keit.go:

59 func getEmbeddedValue(instanceType string) (float64, error) {
60         url := fmt.Sprintf("http://boaviztapi-service:5000/v1/cloud/instance?provider=aws&instance_type=%s&verbose=false&duration=43800&criteria=gwp", instanceType)

43800/hour per day/days per year.
43800/24/365 = 5 years

From: https://api.boavizta.org//docs#/cloud/instance_cloud_impact_v1_cloud_instance_get :
DurationUsage impacts can be given as a router parameter, in hours. If no duration is given, the impact is assess for the all life duration of the asset.
