Frank Schroeder 119f6a1ed7 rpc: monkey patch fix for data races for localState
The tests that use the localState of the agent access the internal
variables and call methods which are not guarded by locks creating
data races in tests. While the use of internal variables is somewhat
easy to spot the fact that not all methods are thread-safe is a
surprise.

A proper fix requires the localState struct to be moved into its own
package so that tests in the agent can only access the external
interface.

However, the localState is currently dependent on the agent.Config
which would create a circular dependency. Therefore, the Config
struct needs to be moved first for this to happen.

This patch literally monkey patches the use of the lock around the
cases which have data races and marks them with a
// todo(fs): data race comment.

Frank Schroeder 1c75cf1af5 pkg refactor
command/agent/*                  -> agent/*
    command/consul/*                 -> agent/consul/*
    command/agent/command{,_test}.go -> command/agent{,_test}.go
    command/base/command.go          -> command/base.go
    command/base/*                   -> command/*
    commands.go                      -> command/commands.go
