Add software manager support to install packages

[vaishnavibhat]

Add a function install_distro_packages() that will check for the distro and install the packages based on the version.

@vaishnavibhat

1. rename to install_package
2. make sure you also add check_package
3. alos uninstall_package
4. make sure they are refelected in other test cases like OptestkernelTest, InstallUpstream...

[abdhaleegit]

check_package is basically a utility to called in test before install or uninstall..

so check_package should return true if already installed, false if not installed.
