Review request for Ambari, Alejandro Fernandez, Nate Cole, Tom Beerbower, and 
Yurii Shylov.


Bugs: AMBARI-9375
    https://issues.apache.org/jira/browse/AMBARI-9375


Repository: ambari


Description
-------

When performing distribute repositories/install packages action, we install 
some packages one by one. If installation of some package fails, all previously 
installed packages are removed.
The risk here is to accidentally (e.g. in case of script bug) remove some 
essential packages.
We might want to add some check to remove only packages that have stack version 
string in their name. Removing them should be enough in most cases since shared 
packages tend to be installed from HDP-UTILS repo.
