Kostiantyn Kalynovskyi a4107e7f1d Allow to use variable substitution for cluster-api components
There are 2 ways to define variables for substitution:

1) Define them as Environment variables and set EnvVars: true
in clusterctl object

2) Define them in additional-vars map in clusterctl object

Also adds possibility not to substitute variables if they are not defined in
in additional-vars or in environment for specific provider. But be aware,
if these variables are defined they will be substituted even if
variable-substitution: true
