As discussed, moving out the network test from CT run.

Note:

Currently the network test are broken, so we are disabling here.

Network manager is getting refactored openbmc/openbmc-test-automation#396
and the test automation equivalent github task to automate this
openbmc/openbmc-test-automation#396

Resolves openbmc/openbmc-test-automation#397
