fix: when the user specifies a replicas other than 2 it is not properly reflected in the Helm chart values.yaml

[HarikrishnanBalagopal]

Bug

Steps to reproduce

1. Run move2kube plan -s src and move2kube transform
2. Specify a different number of replicas

? Provide the minimum number of replicas each service should have
ID: move2kube.minreplicas
Hints:
- If the value is 0 pods won't be started by default

 33

Expected behaviour

The output yamls and helm chart values.yaml should have the replicas set to 33

Actual behaviour

In the output deploy/yamls/ all the Deployment yamls have the replicas set to 33.
In the output deploy/yamls-parameterized/ folder has Helm chart, Kustomize and Openshift Template all of which have replicas set to 2.

This is because the default value in a parameterizer yaml always replaces the original value at the location.

Fix

Add a new option to allow keeping the original value if present.
