Description of problem:

When non-alphanum characters are used as parameters to atomic command for example when passwords are passed in, atomic might fail.

Version-Release number of selected component (if applicable):

atomic-1.6-6.gitca1e384.el7.x86_64

How reproducible:

Deterministic.

Steps to Reproduce:
1. Dockerfile:

FROM rhel7
ADD install.sh /bin/install.sh
RUN chmod +x /bin/install.sh
LABEL INSTALL 'docker run --name ${NAME} -e NAME=${NAME} -e IMAGE=${IMAGE} ${IMAGE} /bin/install.sh'

2. install.sh:

#!/bin/bash
for i in "$@" ; do
	printf '%q\n' "$i" >> /run/install-options
done
cat /run/install-options

3. Build image: docker build -t escapes .
4. Run: atomic install escapes --test 'asdf asdf'
5. Run: atomic install escapes --test 'asdf&asdf'
6. Run: atomic install escapes --test ježek
7. Run: atomic install escapes --test 'asdf"asdf'
8. Run: atomic install escapes --test "asdf'asdf"

Actual results:

# atomic install escapes --test 'asdf asdf'
docker run --rm --name escapes -e NAME=escapes -e IMAGE=escapes escapes /bin/install.sh --test 'asdf asdf'
--test
asdf\ asdf
# atomic install escapes --test 'asdf&asdf'
docker run --rm --name escapes -e NAME=escapes -e IMAGE=escapes escapes /bin/install.sh --test 'asdf&asdf'
--test
asdf\&asdf
# atomic install escapes --test ježek
'ascii' codec can't decode byte 0xc5 in position 3: ordinal not in range(128)
# atomic install escapes --test 'asdf"asdf'
/bin/sh: -c: line 0: unexpected EOF while looking for matching `''
/bin/sh: -c: line 1: syntax error: unexpected end of file
# atomic install escapes --test "asdf'asdf"
/bin/sh: -c: line 0: unexpected EOF while looking for matching `''
/bin/sh: -c: line 1: syntax error: unexpected end of file

Expected results:

# atomic install escapes --test 'asdf asdf'
docker run --rm --name escapes -e NAME=escapes -e IMAGE=escapes escapes /bin/install.sh --test 'asdf asdf'
--test
asdf\ asdf
# atomic install escapes --test 'asdf&asdf'
docker run --rm --name escapes -e NAME=escapes -e IMAGE=escapes escapes /bin/install.sh --test 'asdf&asdf'
--test
asdf\&asdf
# atomic install escapes --test ježek
docker run --rm --name escapes -e NAME=escapes -e IMAGE=escapes escapes /bin/install.sh --test 'ježek'
--test
ježek
# atomic install escapes --test 'asdf"asdf'
docker run --rm --name escapes -e NAME=escapes -e IMAGE=escapes escapes /bin/install.sh --test 'asdf"asdf'
--test
asdf\"asdf
# atomic install escapes --test "asdf'asdf"
docker run --rm --name escapes -e NAME=escapes -e IMAGE=escapes escapes /bin/install.sh --test asdf\'asdf
--test
asdf\'asdf

and no error reported.
