Add resource limits for spark dependencies cronjob

Fixes #598

One of the e2e tests for Kubernetes failed, so I just restarted it. Almost immediately, I saw this in the logs:

git checkout --progress --force 76143e9bd1c40fc0b71fd45a987c80b9db0a9096
##[error]fatal: reference is not a tree: 76143e9bd1c40fc0b71fd45a987c80b9db0a9096
Removed matchers: 'checkout-git'
##[remove-matcher owner=checkout-git]
##[error]Git checkout failed with exit code: 128
##[error]Exit code 1 returned from process: file name '/home/runner/runners/2.157.0/bin/Runner.PluginHost', arguments 'action "GitHub.Runner.Plugins.Repository.CheckoutTask, Runner.Plugins"'.

Not sure what's going on, but could you try to rebase and update this PR?

Opened actions/checkout#23 to track this failure.

Could you please add a test?

I think other components by default use the resources specified at the root level of the spec. We should consider doing the same here.

[rubenvp8510]

Done!

@pavolloffay Tests added.

@rubenvp8510 could you please share an example of how a Jaeger resource would look like (yaml)? I am not sure about how the golang ResourceRequirements maps to the yaml (I see the TestSparkDependenciesResources in the code but I can't see the mapping to yaml either).

I am particularly interested in increasing the request/limits of the jaeger-spark-dependencies pods. The official docs omit the info about it in the "Configuring the Custom Resource" section.

Thank you.
