RichardsMechanics anisotropic permeability

The original tensor is rotated by approximately 30 degree.

Reuse the material property.
Drop <intrinsic_permeability> tag from prj files.

In case of multiple values given under the <value>
tag, the error was not conclusive. Parsing the value
as vector, allows checking of the size now.

Shear strains epsilon_xz and epsilon_yz added as secondary variables.

Migrate LFS from GitLab to Artifactory

The timeout is maximum runtime for one benchmark. Was 15 minutes before.

Introducing ogs-container-generator

Current staggered scheme implementation proved to be
much better than the monolithic implementation, which
fails to predict failure in a shear test.

[CMake] Replace OGS_BUILD_TESTS with BUILD_TESTING

[Jenkins] Suppressed remaining warnings.

BUILD_TESTING is a CMake convention used widely.

Needed for the large tests to finish.

[Conan] Explicitly use lzma/5.2.4@bincrafters/stable
