Modified the info command (both text and JSON output) to display the archive ID and minimum/maximum WAL currently present in the archive for the current and prior, if any, database cluster version.

* More optimized container suite that greatly improves build time.
* Added static Debian packages for Devel::Cover to reduce build time.
* Add deprecated state for containers. Deprecated containers may only be used to build packages.
* Remove Debian 8 from CI because it does not provide additional coverage over Ubuntu 14.04 and Ubuntu 16.04.
Refactor storage layer to allow for new repository filesystems using drivers. (Reviewed by Cynthia Shang.)
Refactor IO layer to allow for new compression formats, checksum types, and other capabilities using filters. (Reviewed by Cynthia Shang.)
* Full coverage is verified when specified.
* Modules marked with partial coverage will error if they are actually fully covered.
* Simplified test representation is DefineTest.
* Added new representation for queries in DefineTest and added API functions.
* Update modules using DefineTest to use new API.
* Automated builds of Debian packages for all supported distributions.
* Added --dev option to aggregate commonly used dev options.
* Added --no-package option to skip package builds.
* C library and packages are built by default, added -smart option to rebuild only when file changes are detected.
* The --libc-only option has been changed to --build-only now that packages builds have been added.
This option allows pgBackRest to validate page checksums in data files when checksums are enabled on PostgreSQL >= 9.3. Note that this functionality requires a C library which may not initially be available in OS packages. The option will automatically be enabled when the library is present and checksums are enabled on the cluster.
Controls whether console log messages are sent to stderr or stdout. By default this is set to warn which represents a change in behavior from previous versions, even though it may be more intuitive. Setting log-level-stderr=off will preserve the old behavior.
Suggested by Sascha Biberhofer.
Master and standby can both be configured on the backup server and pgBackRest will automatically determine which is the master. This means no configuration changes for backup are required after failing over from a master to standby when a separate backup server is used.
