Add connection-based configuration option that toggles automatic CCSID manipulation

[sbdev003]

Is your feature request related to a problem? Please describe.
This request is related to an issue I encountered and reported in:
All files in stream file deployment path blindly set to CCSID 1208 after deploy #2126.

Basically, the feature delivered with PR: Set CCSID of deployed files to 1208 if needed #2015 causes the CCSID of every file in the deployment path (including subdirectories) to be changed to 1208.
I have a use case where some files in the deploy hierarchy must maintain specific CCSIDs.

Describe the solution you'd like
I would like to have a new connection-based configuration option that toggles the automatic CCSID manipulation.

Describe alternatives you've considered

• Restructure legacy project to avoid issues (not possible)
• Post-deployment re-manipulation of CCSIDs

Additional context
Steps to reproduce the issue are provided in the original issue:
All files in stream file deployment path blindly set to CCSID 1208 after deploy #2126

• New option in connection settings to set CCSID automatically to UTF8 (enabled by default)
• add logic to check if new option is enabled here: https://github.com/codefori/vscode-ibmi/blob/master/src/api/local/deployment.ts#L243
