This commit adjusts the build flags to include version information in the LDFLAGS using the -X options. Additionally this makes the information recorded at build time more comprehensive. All build information can now be obtained via the `authelia build` command, and the `authelia version` command is now `authelia --version`. Lastly this adjusts the Dockerfile to utilize docker cache more effectively.
This PR changes the suites tests so if go test -short is used, they are skipped per go standards and a message is displayed. Additionally removed some redundant types from suite_high_availability_test.go and adjusted a warning about a nil req var.
* [MISC] Add missing CLI suite test
* Add missing test for `authelia version` command in CLI suite.
* Standardise logger calls and swap CSP switch order
This change adds a new integration testing suite "CLI".
The intent of this suite is to test, validate and capture coverage for Authelia's commands via the CLI.
