Fabian Reinartz 5b30bdb610 Change TargetProvider interface.
This commit changes the TargetProvider interface to use a
context.Context and send lists of TargetGroups, rather than
single ones.

Julius Volz d88aea7e6f Fix SD mechanism source prefix handling.
The prefixed target provider changed a pointerized target group that was
reused in the wrapped target provider, causing an ever-increasing chain
of source prefixes in target groups from the Consul target provider.

We now make this bug generally impossible by switching the target group
channel from pointer to value type and thus ensuring that target groups
are copied before being passed on to other parts of the system.

I tried to not let the depointerization leak too far outside of the
channel handling (both upstream and downstream) because I tried that
initially and caused some nasty bugs, which I want to minimize.
