RHEL jenkins linux dependency update

Update Java

• download latest jdk17 for linux and copy to a tree in /opt/jdk17
• edit build.sh in client gui build area to set correct JAVA_HOME path

Update Python

• download python source
• on RHEL7 there is an issue with openssl versions. Open ssl 1.1 can be installed from yum, but will not be in the right directory for python. Make sure you install the openssl11-dev and openssl11-static packages as we will link statically to it
• create a /usr/local/openssl11 with an include directory linked to /usr/include/openssl11 and a lib64 directory linked to /usr/lib64/openssl11
• configure with

env LDFLAGS="-L/usr/local/openssl11/lib64 -Wl,-Bstatic -lssl -lcrypto -Wl,-Bdynamic" ./configure --prefix=/usr/local/python --with-openssl=/usr/local/openssl11

Note that passing --enable-optimizations lead to a subsequent build failure

• now type make to build
• finally sudo rm -fr /usr/local/python and sudo make insytall
