Bazel: Introduce .bazelversion and update to 0.29.1 The minimum required bazel version is defined in the WORKSPACE and is checked at build time. However, to support the bazelisk wrapper, we need to define the version in .bazelversion. Bazelisk will automatically switch to that version (downloading it if necessary). Add a .bazelversion file, and introduce the mechanism to consume it in the WORKSPACE rather than defining the version in two separate places. When bazel is used directly, it still checks that the minimum version is used. When bazelisk is used, it will switch to the exact required version. Bump the bazel version up to 0.29.1 as the currently specified minimum version (0.19.0) doesn't work with this new setup. Based on [1] by David Ostrovsky.
