Wait for state

[konstantinvlasenko]

|wait|$x -eq $true|

It would be a really useful addition!

the wait meaning is it does poll every 1 second the expression value. As soon as it becomes $true it stops polling. If any $error happens it stops polling and returns $error. If the expression does not become $true in a minute, it stops polling and returns a Timeout error.

Good idea! Would be good to have ability to specify timeout.
