Populate sequences data using test-data-populator

[erlendvollset]

Currently the data used for the sequences integration tests is populated manually. This should script should be rewritten into the test-data-populator so we ensure that the data is always there.

Are populators based on the old api/sdk only?

[erlendvollset]

Populators are based only on old SDK. This issue can wait until we have moved the populator to v1.

We actually want to get away from using the test-data-populator as much as we can, so closing this.
