Unlink log analytics workspace and automation account

[picccard]

Overview/Summary

Adds option to not link the log analytics workspace with the automation account.

If the centralized workspace got the solution 'Updates', then the automation account will charge $6 for each non-azure VM (on-prem VM) that sends logs to the workspace. The non-azure VMs that shows up in the Configuration Management -> Inventory section of the automation account will result in cost.
