Read nuxeo configuration into an associative array

nxconfig.sh

# Get nuxeo config parameters as <name>=<value> pairs, one per line.
# grep gets rid of other output.
# Perform replacement so that the results can be assigned to an associative array.

    nuxeoctl --get-regexp config '.' |
    grep '=' |
    sed -r 's/([^=]*)=(.*)/\[\1\]="\2"/')

# Assign transformed results to an associative array.
declare -A CONFIG
