Fixed Blue/Green Strategy Ingress Route-Method Glitch (#217)

* Added some tests, not sure what else to try but gonna think of more examples * forgot some files * reverted package-lock.json * Added empty dir test * Cleaned up some extra spaces * Add node modules and compiled JavaScript from main * forgot to actually include functionality * removed unnecessary files * Update .gitignore * Update .gitignore * Update .gitignore * thx david * renamed searchFilesRec * integrations test fix * added examples to README * added note about depth * added additional note * removed ticks * changed version string * removed conflict on readme * Added tests for bluegreen helper and resolved issue with ingress not being read correctly, still have to figure out why new services aren't showing up * resolved services name issue * looks functional, beginning refactor now * refactored deploy methods for type error * Removed refactor comments * prettier * implemented Oliver's feedback * prettier * added optional chaining operator * removed refactor comment Co-authored-by: Jaiveer Katariya <jaiveerkatariya@Jaiveers-MacBook-Pro.local> Co-authored-by: Oliver King <oking3@uncc.edu> Co-authored-by: Jaiveer Katariya <jaiveerkatariya@Jaiveers-MBP.lan>
