feat(cli): Update Kamel bind step index in properties to start at 1 instead of 0

[gansheer]

fixes #2586

Motivation

The kamel bind command uses 0 index start for the definition of step properties :

kamel bind ... --step my-step-1 --step my-step-2 -p step-0.my-key=value1 -p step-1.my-key=value2

Having an index start at 1 is more user friendly :

kamel bind ... --step my-step-1 --step my-step-2 -p step-1.my-key=value1 -p step-2.my-key=value2

Modifications

• Modify the transformation from command to spec for steps in biding command code
• Add a unit test on step values

Release Note
