Downgrade the version of github.com/prometheus/client_golang to 1.7.1 to avoid the compile error in mac

The version 1.8.0 of "github.com/prometheus/client_golang" bumps up lib "golang.org/x/sys" which referenced by "github.com/docker/docker@1.4.2". The changes of "golang.org/x/sys" causes the compile error in mac

-Accessors
---
-
-If you have structs in your parameters, you can access their fields and methods in the usual way. For instance, given a struct that has a method "Echo", present in the parameters as `foo`, the following is valid:
-
-	"foo.Echo('hello world')"
-
-Fields are accessed in a similar way. Assuming `foo` has a field called "Length":
-
-	"foo.Length > 9000"
-
-Accessors can be nested to any depth, like the following
-
-	"foo.Bar.Baz.SomeFunction()"
-
-However it is not _currently_ supported to access values in `map`s. So the following will not work
-
-	"foo.SomeMap['key']"
-
-This may be convenient, but note that using accessors involves a _lot_ of reflection. This makes the expression about four times slower than just using a parameter (consult the benchmarks for more precise measurements on your system).
-If at all reasonable, the author recommends extracting the values you care about into a parameter map beforehand, or defining a struct that implements the `Parameters` interface, and which grabs fields as required. If there are functions you want to use, it's better to pass them as expression functions (see the above section). These approaches use no reflection, and are designed to be fast and clean.

 Logrus is a structured logger for Go (golang), completely API compatible with
 the standard library logger.
 
-**Logrus is in maintenance-mode.** We will not be introducing new features. It's
-simply too hard to do in a way that won't break many people's projects, which is
-the last thing you want from your Logging library (again...).
-
-This does not mean Logrus is dead. Logrus will continue to be maintained for
-security, (backwards compatible) bug fixes, and performance (where we are
-limited by the interface). 
-
-I believe Logrus' biggest contribution is to have played a part in today's
-widespread use of structured logging in Golang. There doesn't seem to be a
-reason to do a major, breaking iteration into Logrus V2, since the fantastic Go
-community has built those independently. Many fantastic alternatives have sprung
-up. Logrus would look like those, had it been re-designed with what we know
-about structured logging in Go today. Check out, for example,
-[Zerolog][zerolog], [Zap][zap], and [Apex][apex].
