Yong Tang b898bdd8c2 Remove duplicate keys in labels of docker info ...

This fix tries to address the issue raised in 24392 where
labels with duplicate keys exist in `docker info`, which
contradicts with the specifications in the docs.

The reason for duplicate keys is that labels are stored as
slice of strings in the format of `A=B` (and the input/output).

This fix tries to address this issue by checking conflict
labels when daemon started, and remove duplicate labels (K-V).

The existing `/info` API has not been changed.

An additional integration test has been added to cover the
changes in this fix.

This fix fixes 24392.
