Description

Eager resolution of configs can result in inconsistent application of substitutions. For example: if job template has the following configs:

key1 = "val1"

key2 = ${key1}

and if key1 is dynamically overridden (e.g. via FlowSpec) to "val2", then the current behavior will result in:

key1="val2"

key2="val1" 

The correct behavior should be to have both key1 and key2 to be set to "val2".
