chore: add tests to ExecuteWithClient for pipelines cmds (#2111)

* refactor: no need to set a default table style

This line is redundant.

* add tests for list pipeline

* fix imports

* rename test file

* empty response test

* test pipelines describe

* move services to single file

* rather do this instead

* create testutils and reorganize internal

* update pipelines ls test

* update

* add test for connectors ls

* refactor connector list test

* test connectors describe

* test processor describe

* test processorplugins describe

* test connectorplugins describe

* compare with entire table

* refactor tests to compare with entire table

* test processors ls

* test procesor plugins ls

* test connectorplugins ls

* remove unneeded call

no need https://github.com/uber-go/mock/blob/v0.5.0/gomock/controller.go#L80-L104

* better test

* separate concerns
