Feat/datadog apm (#466)

* build(deps): add dd-trace

* feat: use dd-trace

* ci: update ci

* fix: move dd-trace to top of file

* ci: test sed command

* fix(ci): add ebextensions to zip command

we need to explicitly provide the folder path in order for ebextensions to be zipped.
the injection step has been shifted infront so that the deploy folder will have the key.
this also reverts the sed command change which doesn't work on bash

* Fix: rebase errors
