Packages are often also installed in both the pre-install.d and post-install.d phases. This patch expands the package-installs element to support declarative package support for these phases in addition to the existing support for install.d. The actual install/uninstall logic is moved to common scripts under bin/ so that it can be reused across the different phases. Change-Id: Id51d0bbad232737fc8b5ffaf016dec50cd5b66c9
