[Bug] [zos_blockinfile] Can quotes in content can be supported

[ddimatos]

SUMMARY

This is a research item to identify the cases we might be missing.
Today in zos_blockinfle we support no quotes in the content block, in fact if we see them we strip them out (issue #303).

In discussion it came up that possibly this might need to be supported:

- name: Update USS script
      zos_blockinfile:
        src: "/u/scripts/script.sh"
        insertafter: "EOF"
        block: |
             cat "//'{{ DS_NAME }}'"
             cat "//'{{ DS_NAME_2 }}'"
      register: result
    - name: Response
      debug:
        msg: "{{ result }}"

This could also easily apply to a data set of type PDS/E where a member might have content like wanting to append some cat statements.

//BPXSLEEP JOB MSGCLASS=A,MSGLEVEL=(1,1),NOTIFY=&SYSUID,REGION=0M
//USSCMD EXEC PGM=BPXBATCH
//STDERR  DD SYSOUT=*
//STDOUT  DD SYSOUT=*
//STDPARM DD *
SH ls -la /;
sleep 30;
/*
// 

This could possibly impact ZOAU dmod dependency depending on the research.
Review applicable ZOAU JIRA 9120

[ddimatos]

It appears ZOAU 1.2.2 resolved the issue in their python api's for issue 9120, this work item now should evaluate that fix from ZOAU an then remove the logic in the zos_blockinfile module that strips quotes.
