Enable forward compatibility for AutoML models

Adopt v10.2 AutoML Worker or model to IA Cloud v10.1.6

For OOTB or models based on Python 2, no additional action is required. Everything is supposed to work by default.

For models based on Python 3, proceed as described below:

1. Install Python 3.7 on your Agents.

   Expand for installation code

    ```
    sudo yum -y install yum-utils
    sudo yum -y groupinstall development
    sudo yum -y install \
        wget \
        zlib-devel \
        gcc \
        zlib-devel \
        bzip2 \
        bzip2-devel \
        readline-devel \
        sqlite \
        sqlite-devel \
        openssl-devel \
        tk-devel \
        libffi-devel \
        xz-devel
    parent_directory=/usr/local/python
    mkdir -p $parent_directory
    cd $parent_directory
    wget https://www.python.org/ftp/python/3.7.9/Python-3.7.9.tgz
    tar -zxvf Python-3.7.9.tgz
    cd Python-3.7.9
    ./configure --prefix=$parent_directory/python3.7.9 --enable-optimizations
    make clean
    make
    make install
    cd $parent_directory/python3.7.9/bin
    ln -s python3.7 python
    ln -s pip3.7 pip
    new_shebang='#!/usr/bin/env python3.7'
    escaped_new_shebang=$(printf '%s\n' "$new_shebang" | sed -e 's/[\/&]/\\&/g')
    sed -i "1s/.*/$escaped_new_shebang/" pip
    cd $parent_directory
    zip -r python3.7.9.zip python3.7.9/
    ```
   

2. Add Python dependencies:

   python3.7 -m pip install six==1.15.0
   python3.7 -m pip install numpy==1.18.5
   python3.7 -m pip install spacy==2.3.2
   python3.7 -m pip install scikit-learn==0.23.1
   python3.7 -m pip install mxnet==1.6.0
   

3. Add the following variables to /opt/workfusion/environment.sh:

   export PYTHONHOME=
   export PYTHONPATH=
   export PATH=
   

The final environment.sh file should look like this:

environment.sh     [-M--] 32 L:[  1+33  34/ 34] *(2175/2239b) 0109 0x06D                                                                                                              
export PYTHONHOME=/usr/local/python/python3.7.9/
export PATH=/usr/local/python/python3.7.9/bin:$PATH
export PYTHONPATH=/usr/local/python/python3.7.9/lib:/usr/local/python/python3.7.9/lib64
