ENH: Establish basic test pipeline

Summary

As explained in https://gitlab.indiscale.com/caosdb/customers/lfpb/management/-/issues/359, this MR introduces integration tests and a basic pipeline that's automatically triggered by commits in caosdb-julialib.

Focus

Mainly pipeline stuff. Since it is not common practice to have tests and implementation in separate packages, there are two ways of using this package. For testing the remote package CaosDB.jl, mainly the way to go for the pipeline, this package can be used as any other Julia package, while for testing of a local CaosDB.jl, runtests.jl has either to be used separately or the local CaosDB.jl package has to be added as a test dependency manually (see below).

Test Environment

Mainly verify that the pipeline is correctly triggered by caosdb-julialib, that the correct branches are used, and that everything runs smoothly.

When executed from the CaosDBIntegrationTest.jl package, the package will try and use the CaosDB.jl package in a fitting branch from remote, so if you want to execute the integration tests with your local CaosDB.jl installation, do

julia test/runtests.jl

Note that without specifying the verbosity, there won't be (test) output if the tests succeed. Alternatively, you can add your local package to the test dependencies and then use Pkg.test as usual, i.e.,

julia> ] activate ./test
julia> ] add path/to/local/caosdb-julialib
julia> ] activate .
julia> ] test
