Description

Most IIS functional tests that are quarantined, are a result of some form of:

```
System.AggregateException : Operation did not succeed after 12 retries (Sequence contains more than one element) (Sequence contains more than one element) (Sequence contains more than one element) (Sequence contains more than one element) (Sequence contains more than one element) (Sequence contains more than one element) (Sequence contains more than one element) (Sequence contains more than one element) (Sequence contains more than one element) (Sequence contains more than one element) (Sequence contains more than one element) (Sequence contains more than one element)
---- System.InvalidOperationException : Sequence contains more than one element
---- System.InvalidOperationException : Sequence contains more than one element
---- System.InvalidOperationException : Sequence contains more than one element
---- System.InvalidOperationException : Sequence contains more than one element
---- System.InvalidOperationException : Sequence contains more than one element
---- System.InvalidOperationException : Sequence contains more than one element
---- System.InvalidOperationException : Sequence contains more than one element
---- System.InvalidOperationException : Sequence contains more than one element
---- System.InvalidOperationException : Sequence contains more than one element
---- System.InvalidOperationException : Sequence contains more than one element
---- System.InvalidOperationException : Sequence contains more than one element
---- System.InvalidOperationException : Sequence contains more than one element
```

Which looks like a result of apphost config getting corrupted in a bad state, local retries will not help this situation.

This is the main tracking issue for finding the root cause
