Update apache/thrift to 0.11.0 and remove pinning (#1317)

The `apache/thrift` recently released a new version of `0.11.0` several days ago. This release is compatible with other packages and as such, there is no need to pinning the `apache/thrift` to `master` anymore in Gopkg.toml. This fix removes the pinning of `apache/thrift` in Gopkg.toml, and updates all dependencies of coredns. Signed-off-by: Yong Tang <yong.tang.github@outlook.com>

-# The plan9 package provides access to the raw system call
-# interface of the underlying operating system.  Porting Go to
-# a new architecture/operating system combination requires
-# some manual effort, though there are tools that automate
-# much of the process.  The auto-generated files have names
-# beginning with z.
-#
-# This script runs or (given -n) prints suggested commands to generate z files
-# for the current system.  Running those commands is not automatic.
-# This script is documentation more than anything else.
-#
-# * asm_${GOOS}_${GOARCH}.s
-#
-# This hand-written assembly file implements system call dispatch.
-# There are three entry points:
-#
-# 	func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
-# 	func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr);
-# 	func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
-#
-# The first and second are the standard ones; they differ only in
-# how many arguments can be passed to the kernel.
-# The third is for low-level use by the ForkExec wrapper;
-# unlike the first two, it does not call into the scheduler to
-# let it know that a system call is running.
-#
-# * syscall_${GOOS}.go
-#
-# This hand-written Go file implements system calls that need
-# special handling and lists "//sys" comments giving prototypes
-# for ones that can be auto-generated.  Mksyscall reads those
-# comments to generate the stubs.
-#
-# * syscall_${GOOS}_${GOARCH}.go
-#
-# Same as syscall_${GOOS}.go except that it contains code specific
-# to ${GOOS} on one particular architecture.
-#
-# * types_${GOOS}.c
-#
-# This hand-written C file includes standard C headers and then
-# creates typedef or enum names beginning with a dollar sign
-# (use of $ in variable names is a gcc extension).  The hardest
-# part about preparing this file is figuring out which headers to
-# include and which symbols need to be #defined to get the
-# actual data structures that pass through to the kernel system calls.
-# Some C libraries present alternate versions for binary compatibility
-# and translate them on the way in and out of system calls, but
-# there is almost always a #define that can get the real ones.
-# See types_darwin.c and types_linux.c for examples.
-#
-# * zerror_${GOOS}_${GOARCH}.go
-#
-# This machine-generated file defines the system's error numbers,
-# error strings, and signal numbers.  The generator is "mkerrors.sh".
-# Usually no arguments are needed, but mkerrors.sh will pass its
-# arguments on to godefs.

-// Package plan9 contains an interface to the low-level operating system

-// by default, godoc will display the OS-specific documentation for the current
-// system. If you want godoc to display documentation for another
-// system, set $GOOS and $GOARCH to the desired system. For example, if
-// you want to view documentation for freebsd/arm on linux/amd64, set $GOOS
-// to freebsd and $GOARCH to arm.
-// The primary use of this package is inside other packages that provide a more
-// portable interface to the system, such as "os", "time" and "net".  Use
-// those packages rather than this one if you can.
-// For details of the functions and data types in this package consult
-// the manuals for the appropriate operating system.
-// These calls return err == nil to indicate success; otherwise
-// err represents an operating system error describing the failure and
-// holds a value of type syscall.ErrorString.
