If container's config.json have `"terminal": true` setting in its
"process" section, runc exec assumes that stdin (fd 0) is a terminal
and tries to use it.
This leads to the following error in case stdin is not a terminal:
> ERRO[0000] exec failed: provided file is not a console
So, even if -t/--tty is not set, exec uses stdin as a terminal.
It does not help that urfave/cli v1 parser we use does not allow
to use `-t no` or `-t false`.
Since the settings in config.json is probably for the container run/start,
not for the auxiliary process started inside a container with exec, do
not use a setting from there, only treating stdin as a terminal in case
`-t` is explicitly given.
Tests that use runc exec with a terminal are amended with -t.

Previously we weren't testing that detached io works properly -- which
will be quite important in the case for rootless containers.

Enable several previously disabled tests (for the idmap execution mode)
for rootless containers, in addition to making all tests use the
additional mappings. At the moment there's no strong need to add any
additional tests purely for rootless_idmap.

This moves all console code to use github.com/containerd/console library to
handle console I/O. Also move to use EpollConsole by default when user requests
a terminal so we can still cope when the other side temporarily goes away.

This adds targets for rootless integration tests, as well as all of the
required setup in order to get the tests to run. This includes quite a
few changes, because of a lot of assumptions about things running as
root within the bats scripts (which is not true when setting up rootless
containers).

Add some tests to ensure that we always get a proper console (created
inside the container). This is done by checking that the
/proc/self/fd/[012] "symlinks" are always referencing something in
/dev/pts/*.
This patch is part of the console rewrite patchset.
