Removes remoteConsuls in favor of the new router.
This has the next wave of RTT integration with the router and also
factors some common RTT-related helpers out to lib. While we were
in here we also got rid of the coordinate disable config so we don't
need to deal with the complexity in the router (there was never a
user-visible way to disable coordinates).

Sean Chittenden da298f527d Guard against divide by zero in lib.RandomStagger()
While I'm at it, add a DurationMinusBufferDomain() function to calculate the min/max for a given call to DurationMinusBuffer() in order to keep the implementation details self-contained.

Sean Chittenden 3a6be9cab0 Add a helper function DurationMinusBuffer() to calculate an interval
used to schedule a TTL check.  e.g.

d := lib.DurationMinusBuffer(60 * time.Duration, 10 * time.Second, 16)

will return a duration between 46.875s and 50s.

Sean Chittenden 9fb64ab114 Allow adjusting the number of DNS records in a response...
Based on work done by @fusiondog in #1583, extend the concept to use an integer instead of a boolean.

Fixes: #1583 && #1481

Sean Chittenden 4382c1f7aa Always seed math/rand on consul startup
Required for jitter calcs.  This could be done in consul/agent, but this makes it clear it is done only once process-wide.

Sean Chittenden 7af6a94edb Factor out duplicate functions into a lib package
Consolidate code duplication and tests into a single lib package.  Most of these functions were from various **/util.go functions that couldn't be imported due to cyclic imports.  The consul/lib package is intended to be a terminal node in an import DAG and a place to stash various consul-only helper functions.  Pulled in hashicorp/go-uuid instead of consolidating UUID access.
