  [META] Automate artifact signing with OpensearchSignerClient for linux
  ### Is your feature request related to a problem? Please describe
  
  Signing currently is a long painstaking process. It needs to be automated to save time when releasing artifacts. We need a tool to be able to sign all artifacts - 
  - opensearch
  - opensearch-dashboards
  
  ### Describe the solution you'd like
  
  Use the existing `Signer.py` class to sign the artifacts and generate ".sig" file along with ".asc" files.
  
  ### Tasks
  - [x] #1382
  - [x] #1383
  - [x] #1385
  
  ### Acceptance Criteria
  - [ ] User is able to provide the artifact directory and tool is able to sign all the artifacts in the directory
  - [ ] User is able to pass the artifact path and the tool is able to sign the artifact
  
  ### Next Steps
  Next steps would include to extend this process over for mac and windows
