Add parameter to allow importing a module array

[sscchh2001]

When using this script to update Az modules in Azure China cloud, it will only import Az.Accounts module. It is inconvenient for customer because if they want other Az modules, they cannot import the modules with this script.

Is it possible to by default import Az.Compute and Az.Storage modules?
Or optionally provide a parameter to allow users to import modules from a module array.
