MGMT-16151: Failed to download installation logs form cluster with 103 nodes

[ammont82]

Related to https://issues.redhat.com/browse/MGMT-16151

Changes the way that UI is downloading installation logs (with file-saver library) because big files don't work in some browsers. The problem is that file-saver try to download logs open a popup and some browsers have popup blockers and then don't work.
