On Python 3, execute() and ssh_execute() now return stdout and stderr as
Unicode. os.fsdecode() is used to stdout and stderr, it uses the locale
encoding with the surrogateescape error handler.
subprocess.Popen(universal_encoding=True) uses the same encoding and
error handler.
This change breaks the backward compatibility, but I believe that
Unicode is more convinient in Python 3 and it is what users expect. In
practice, there is no known (OpenStack) application compatible with
Python 3 using oslo_concurrency.processutils yet.
Add new tests.
This changeset does not change the behaviour on Python 2, only Python 3
is impacted.

Issue: simultaneous usage of 'shell' and 'run_as_root' options led
to error.
Cause: it's actually a concealed TypeError: in 'shell'
mode the command argument is assumed to be a string, elsewhere
a list/tuple.
Fix: the command editing implied by 'run_as_root' is performed
with care taken of above tacit type assumption.

Currently folks end up using os.chdir() (see bug listed below) as
we are not exposing the subprocess.Popen's cwd parameter. It's
better to add a cwd parameter in processutils.execute so folks
do not have to issue chdir() before and after the processutils.
execute and there's less scope for problem as documented in
the bug.

This reverts commit 7c7493feb53429577efca2c4b0380af03ddc149b.
This change breaks the API of execute() and breaks nova's tests.

Lockutils uses %0.3fs for time format, which gives us a convenient
time in milliseconds. Process utils was an unbounded string which
gives us times like:
CMD "cat /proc/31599/cmdline" returned: 0 in 0.00526595115662s execute
The super long time strings are mostly confusing, and millisecond
accuracy should be sufficient for processutils.

Add encoding and errors parameters to execute() and ssh_execute(). By
default, use the locale encoding in strict mode on Python 2, or the
locale encoding with the 'surrogateescape' error handler on Python 3.
Fix also unit tests to use bytes strings for stdin, stdout and stderr.
Without this change, tests are failing with Python 3 when run with:
PYTHON="python -bb" testr run
Using -bb, Python 3 raises a TypeError when a bytes string is casted
to a text string, which occurred in many places.

Move the public API out of oslo.concurrency to oslo_concurrency. Retain
the ability to import from the old namespace package for backwards
compatibility for this release cycle.
