Add minimal CLI - Githubissues

In the past numerous attempts have been made to mitigate interaction with Exasol's BucketFS:

:heavy_check_mark: bucketfs-python: Python, active, used for tests automation of various python projects.
:heavy_check_mark: bucketfs-java: Java, used for tests automation of various java projects.
:question: bucketfs-client: Java, limited functionality, currently not develeoped actively
:x: bucketfs-explorer: Java, GUI application, archived, deprecated Currently contained in official documentation (see DOC-2221)
:x: bucketfs-utils-python: depecated, superseeded by bucketfs-python
:question: shell functions for bash based on CURL requests: only for power users, limited functionality, see below

function bucketfs-password() {
    if [ -z "$1" ]; then
       echo "usage: bucketfs-password <container>"
       return 1
    fi
    BUCKETFS_PASSWORD=$(
    docker exec -it $1 \
           grep WritePass /exa/etc/EXAConf \
        | sed -e "s/.* = //" \
        | tr -d '\r' \
        | base64 -d)
}

function bucketfs-upload() {
    if [ -z "$1" ]; then
       echo "usage: bucketfs-upload <file> [path/in/bucket-fs]"
       return 1
    fi
    if [ -z "$BUCKETFS_PASSWORD" ]; then
       echo "Please set environment variable BUCKETFS_PASSWORD"
       return 1
    fi
    A=2580 # port
    B=$(echo default/$2 | sed -e 's/\/$//') # path
    curl -v -X PUT -T $1 http://w:$BUCKETFS_PASSWORD@localhost:$A/$B/$1
}

Still users struggle and need help from time to time. The current ticket therefore requests to create a minimal CLI solution

convenient and easy to use
acceptable usability with sufficient functionality and at least some guidance for unexperienced users
lightweight with minimal footprint and prerequisites, e.g. frameworks and installations

In summary bucketfs-python seems to be the best candidate. It is used anyway for test automation of various python projects. Currently issue #4 requires to enhance bucketfs-python to list the contents of a folder in BucketFS which could be another building block in order to provide a minimal CLI with very limited effort.
