mongo replset fails when installing packages with t-h-t

[Dan Prince]

Trying to use tripleo-heat-templates to install packages (via EnablePackageInstall) fails because 'mongo' isn't getting installed.
We currently get this error:

Error: Could not prefetch mongodb_replset provider 'mongo': Could not evalute MongoDB shell command: printjson(rs.conf())

---

Simply including the mongodb client manifest should fix it.

    Install mongodb client package

    This resolves an error which can occur when trying to
    create an overcloud without pre-built images. Specifically
    mongodb replset creations fails because there is no 'mongo'
    binary present:

    Error: Could not prefetch mongodb_replset provider 'mongo': Could not
    evalute MongoDB shell command: printjson(rs.conf())

    Simply including the mongodb::client puppet class should resolve
    this issue.
