<p>
The percentage of accounts, per Region, for which this stack operation can fail before Service Catalog stops the
operation in that Region. If the operation is stopped in a Region, Service Catalog doesn't attempt the operation
in any subsequent Regions.

When calculating the number of accounts based on the specified percentage, Service Catalog rounds down to the
next whole number.

Conditional: You must specify either <code>StackSetFailureToleranceCount</code> or
<code>StackSetFailureTolerancePercentage</code>, but not both.
