This reverts commit 334f399ee3, reversing
changes made to 45a5d28bad.
When testing against Windows SSH the Powershell script fails to parse
the newly added if statement.
This change sets the ErrorActionPreference and wraps the script execution in a Try/Catch statement so that the provisioner can capture any errors encountered when running the script. In addition to the try/catch the `&` operator is replaced by the `.` sourcing operator to ensure the script is executed in the same scope as the parent command (so that errors bubble up properly).
Tests after change
```
⇶ ACC_TEST_BUILDERS=amazon-ebs ACC_TEST_PROVISIONERS=powershell go test ./provisioner/powershell/... -timeout=1h
ok github.com/hashicorp/packer/provisioner/powershell 915.865s
```
* Add retry logic so that the provisioner will retry if it fails to upload/execute because of some restart provisioner step
* Add a testConfigWithSkipClean for testing that the provisioner executes the correct commands
* Add a test case for toggling the "skip_clean" config option
It is simply the best/simplest solution and trying to prevent users from passing and integer here would be like opening a can of worms. Because:
* we cannot make mapstructure validate our duration string ( with an UnmarshalJSON func etc.)
* we cannot make mapstructure spit a string instead of a duration and packer will decode-encode-decode config.
* the hcl2 generated code asks for a string, so this will be enforced by default.
Before this commit it was possible to set a duration using an integer or a float. Go's time.Duration is an int64 internally an mapstructure will take advantage of this and load the number as a int64 but `1` means one ns which is unexpected/confusing. To avoid confusion and enforce readability this forces users to pass a string with a unit for a duration; ex "56s".
Revert so that we can merge a different branch that's had more recent work instead
This reverts commit ba518637d4, reversing

Fix a bug in the size of string that was returned when decoding a base64 string
Added tests around encoding and decoding powershell scripts. Used [System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes('powershell commands')) | clip to generate what base 64 strings should look like
