Updated CouchDB Install b/c 1.3 no longer avail on mirrors

For PM=apt-ubuntu, we use the nilya/couchdb-1.3 ppa as done in the travis build.
For PM= Yum-rhel Updated the file location and fit the "make install" prociess within the if statement.
Added wget requirements/apt-packages.txt

The apt-packages requirements were moved to a different directory, but the install script was not updated. This checks to see if the requirements directory exists. If not, it creates the directory and downloads the latest requirements/apt-packages.txt file to be used later in the install.
