Title: Use String.concat in FailoverLoader for performance-critical concatenations of two Strings.

Use String.concat in FailoverLoader for performance-critical concatenations of two Strings.

This has performance improvements in fewer allocations in caliper tests. Javac basically puts concatenations into a StringBuilder of size 16, so all sorts of random resizing goes on. String.concat just allocates one new array sized appropriately. Small thing, but it can make a difference.
