According to your description, I test in my lab. You had better adjust the script format. The following script is mine, it works for me.
cd /tmp
wget http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-9.noarch.rpm
rpm -ivh epel-release-7-9.noarch.rpm
yum install ansible -y
When you don't get expected outcome, you could check /var/log/waagent.log, you will get log as below:
2017/02/07 01:49:53 CustomScriptForLinux started to handle.
2017/02/07 01:49:53 [Microsoft.OSTCExtensions.CustomScriptForLinux-1.5.2.1] cwd is /var/lib/waagent/Microsoft.OSTCExtensions.CustomScriptForLinux-1.5.2.1
2017/02/07 01:49:53 [Microsoft.OSTCExtensions.CustomScriptForLinux-1.5.2.1] Change log file to /var/log/azure/Microsoft.OSTCExtensions.CustomScriptForLinux/1.5.2.1/extension.log

2017/02/07 01:49:54.518685 INFO [Microsoft.OSTCExtensions.CustomScriptForLinux-1.5.2.1] Enable extension.
2017/02/07 01:49:54.541244 INFO [Microsoft.OSTCExtensions.CustomScriptForLinux-1.5.2.1] Launch command:customscript.py -enable
Now, you could check log /var/log/azure/Microsoft.OSTCExtensions.CustomScriptForLinux/1.5.2.1/extension.log
Update: If you lost some file, you could try to uninstall the extension and install it again.
