ACS must be a positive number. The server's concurrency limit (SCL) is divided among the concurrency-controlled priority levels in proportion to their assured concurrency shares. This produces the assured concurrency value (ACV) --- the number of requests that may be executing at a time --- for each such priority level:
	//
	//             ACV(l) = ceil( SCL * ACS(l) / ( sum[priority levels k] ACS(k) ) )

This field holds the ratio of that limit to the level's nominal concurrency limit. When this field is non-nil, it must hold a non-negative integer and the limit is calculated as follows.
	//
	// BorrowingCL(i) = round( NominalCL(i) * borrowingLimitPercent(i)/100.0 )
	//
	// The value of this field can be more than 100, implying that this priority level can borrow a number of seats that is greater than its own nominal concurrency limit (NominalCL). When this field is left `nil`, the limit is effectively infinite.
	BorrowingLimitPercent int32 `json:"borrowingLimitPercent,omitempty"`

	// `lendablePercent` prescribes the fraction of the level's NominalCL that can be borrowed by other priority levels. The value of this field must be between 0 and 100, inclusive, and it defaults to 0. The number of seats that other levels can borrow from this level, known as this level's LendableConcurrencyLimit (LendableCL), is defined as follows.
	//
	// LendableCL(i) = round( NominalCL(i) * lendablePercent(i)/100.0 )
