conmon has many flags that are parsed when it's executed, one of them
is "-c". During PR #510 where we vendor latest kube master code,
upstream has changed a test to call a "ctr execsync" with a command of
"sh -c commmand ...".
Turns out:
a) conmon has a "-c" flag which refers to the container name/id
b) the exec command has a "-c" flags but it's for "sh"
That leads to conmon parsing the second "-c" flags from the exec
command causing an error. The executed command looks like:
conmon -c [..other flags..] CONTAINERID -e sh -c echo hello world
This patch rewrites the exec sync code to not pass down to conmon the
exec command via command line. Rather, we're now creating an OCI runtime
process spec in a temp file, pass _the path_ down to conmon, and have
runc exec the command using "runc exec --process
/path/to/process-spec.json CONTAINERID". This is far better in which we
don't need to bother anymore about conflicts with flags in conmon.
Added and fixed some tests also.

The ocid project was renamed to CRI-O, months ago, it is time that we moved
all of the code to the new name. We want to elminate the name ocid from use.
Move fully to crio.
Also cric is being renamed to crioctl for the time being.

Now that we have support for split std{out,err}, make sure that execsync
will correctly handle the split stdio properly. In addition, extend the
ctr logging test to make sure that the regular container logging is also
split correctly. We can't test !terminal containers because we only have
a single console for both std{out,err}.

The main purpose of these tests is to make sure that the log actually
contains output from the container. We don't test the timestamps or the
stream that's stated at the moment.

"executable file not found in" is part of a runc
specific output when 'runc exec' fails.
This prevents the execsync failure to pass when running
ocid with other runtimes than runc.

The gprc execsync client call doesn't populate `ExecSyncResponse` on
error at all. You just get an error.
This patch modifies the code to include command's streams, exit code
and error direcly into the error. `ocic` will then print useful
infomation in the cli, otherwise it won't.

In several places, we previously didn't output the $output of the
failing command, leading to confusion when debugging. A proper fix is to
alias oci{c,d} in helpers.sh like runC does, but that can come later.
