client: handle commit messages with \0 characters for all commands

Each of the impacted commands will now use the 'json' template,
which they all support as of Mercurial 3.7.3 (the first version
tested in the regression tests).

Note: I tried to add a test with null bytes,
but both hglib and using hg directly through subprocess
rejected adding a commit message with a null byte.

from hglib.util import b

changeset = b('{rev}\\0{node}\\0{tags}\\0{branch}\\0{author}'
              '\\0{desc}\\0{date}\\0')
