os/bluestore: do not set osd_memory_target default from cgroup limit

On the aarch64 box I'm testing, this gives us a value of
7378697629483768832, which is not what we want.

I think we are better off relying on this limit being explicitly set via
environment variables (POD_* by kuberentes/rook) or via the command line.

This partially reverts 5c6b533697814af8acfd9e731a2599b2294687ef, but not
all of it, since we wan to keep the option itself, as it is now used by
common/config.cc when dealing with the POD_MEMORY_LIMIT env var.

ceph-volume: terminal: encode unicode when writing to stdout

python determins the encoding of stdout and stderr based on the LC_CTYPE
and PYTHONIOENCODING env variable, by default, python3's sys.stdout uses
'utf-8' as its encoding, so it will be able to write unicode string even
the stdout is not attached to a tty device. but when it comes to
python2, it will default to ascii if neither of these variabls is set.
so, if we are writing unicode using `_Write` in an environment where
LC_CTYPE and/or PYTHONIOENCODING are using non UTF-8 encoding, it chokes
by raising `UnicodeEncodeError` exception.

in this change, we add a wrapper around `_Write._writer` so it is able
to write unicode string in such a non-unicode-friendly environment.

for more info related the encoding of stdout and stderr, see

common/config: respect POD_MEMORY_REQUEST *and* POD_MEMORY_LIMIT env vars

If a kubernetes pod spec specifies a limit of X, then the pod gets both
the limits.memory and requests.memory resource fields set, and rook passes
those as POD_MEMORY_LIMIT and POD_MEMORY_REQUEST environment variables.

This is a problem if only the limit is set, because we will end up
setting our osd_memory_target (and, in the future, other *_memory_targets)
to the hard limit, and the daemon will inevitably reach that threshold
and get killed.

Fix this by also looking at the POD_MEMORY_LIMIT value, and applying the
ratio (default: .8) to it, and setting our actual target to the min of
that and the POD_MEMORY_REQUEST.

Also, set the "default" target to ratio*limit, so that it will apply in
general when no request is specified.

When both request and limit are 10M, we then see

        "osd_memory_target": {
            "default": "800000000000",
            "env": "800000000000",
            "final": "800000000000"
        },

In a more "normal" situation where limit is 10M and request is 5M, we get

        "osd_memory_target": {
            "default": "800000000000",
            "env": "500000000000",
            "final": "500000000000"
        },

If only limit is specified (to 10M), we get

        "osd_memory_target": {
            "default": "800000000000",
            "final": "800000000000"
        },
