* First commit - made manifests for test deployments, made manifests for i tests for other deployment strategies

* broke down blue/green

* added latest tags to test manifests for new tags

* remade tester

* ready to test bgi

* using all but first index of argv

* careless error with dicts

* added test to namespace

* realized i was silencing error

* indexing containers

* keyerror

* logging bc python errors are weird

* expected still string

* parsed args behaving weirdly

* test seems to be working now, applying changes to other YAMLs now

* blue/green ready to test

* oops

* oops

* Added additional labels to check

* hyphen

* Added our annotations

* lol

* added our labels to services too

* nonetype issue'

* nonetype issue'

* narrowing down parameter

* fixed annotations issue with promote

* adding debhug statement to figure out why services aren't getting annotations

* this should fix annotations issue for service

* not sure why this wasn't caught by intellisense

* should be fixed with removing comma but adding logs in case

* added linkerd install

* verification

* upgraded kubernetes version

* removing crds

* proxy option

* Added smi extension

* logging service

* smi svcs also getting labeled now

* matching ts type

* not sure where stable service is going

* keeping stable service and ts object

* updated tests to reflect keeping ts object

* no green svc after promote

* duh

* lol

* canary work

* canary test ready

* logging for ing, filename for canary

* changed ingress svc key and returning svc files from smi canary deployment

* ts name

* forgot about baseline in first deploy

* *

* *

* smi canary should annotate, fixed cleanup

* typescript issue plus percentage

* forgot to type extra method

* removed cleaned up objects from annotate list

* logging because services aren't getting removed

* moving to try/catch strategy of annotation since deletion can fail silently/with warnings

* moved label to individual

* removing canary service check after promote

* pod ready for testing

* set weights to 1000

* selectors

* *

* percentage

* *

* typing
