Several changes on the workflow overall.
a. Fix up the parsing logic of "GetDeploymentCount" to extract out the deployment id when the compute emulator gets launched. This appears never works
b. Fix up the logic of "GetRoleInfoMessage" of extract out the IIS Express url
c. Plumb through error and output from storage emulator
d. Fix up the inconsistent usage of StandardOutput and StandardError. In the workflow, these 2 variables sometimes was not used only for the purpose the name implies
