Enhancement: don't need to type ssh password twice when docker logs with ssh

- What I did
When use ssh host, docker logs need user to type password twice.

root@dockerdemo:~/gocode/src/github.com/docker/cli# docker -H ssh://localhost logs test1
root@localhost's password: (First time)
root@localhost's password: (Second time)
1:C 11 Oct 03:41:51.863 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
1:C 11 Oct 03:41:51.863 # Redis version=4.0.11, bits=64, commit=00000000, modified=0, pid=1, just started

- How I did it
Because ContainerInspect is behind ContainerLogs, but ContainerLogs don't close the response, so ContainerInspect can't reuse the connection.
So, move ContainerInspect to the ahead of ContainerLogs.

- How to verify it

root@dockerdemo:~/gocode/src/github.com/docker/cli# build/docker -H ssh://localhost logs test1
root@localhost's password: (Just once)
1:C 11 Oct 03:41:51.863 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
1:C 11 Oct 03:41:51.863 # Redis version=4.0.11, bits=64, commit=00000000, modified=0, pid=1, just started

- Description for the changelog
Move ContainerInspect to the ahead of ContainerLogs, so we can reuse docker host connection.
