Fix integration tests

[jevgenigeurtsen]

Updated integration_tests.sh;

• Enabled execution of all integration tests
• Disabled execution of cloud integration tests
• Added another docker instance that has basic auth enabled
• Added multiple collections/cores, just to the default docker instance, required by various integration tests

Solution;

• Fixed failing integration tests
• Added integration tests to SolrNet.Tests to verify if basic auth is working, for both sync and async requests
• Lowered LightInject package version

Wait for #586 to be merged so that I can use LightInject SolrNet extensions to test authentication with sync/async calls. Test code is already in IntegrationfixtureTestAuthtentication, but commented out.

Sorry for the delay here. Now that #586 has been merged could you rebase this?

[jevgenigeurtsen]

Done. Let me know if there is anything I can do.

Hi, thanks but can you rebase it? I see you merged master into this branch, which is the opposite of what I wanted 🙂
i.e. cherry-pick your commits on top of master.

[jevgenigeurtsen]

Ah my bad. I rebased this branch on master and cherry picked the needed commits onto it.
