Replacement for deprecated requireKeytar property in Zowe v3

[t1m0thyj]

In previous Zowe SDK versions, the IProfOpts.requireKeytar property was supported on the ProfileInfo constructor. It is now deprecated:

  const profInfo = new ProfileInfo("zowe", {
    requireKeytar: () => require("@zowe/secrets-for-zowe-sdk").keyring,
  });

When migrating to Zowe V3 (@zowe/cli@8) or a newer version of V2 @zowe/cli@>=7.13), the replacement is to use IProfOpts.credMgrOverride instead:

  const requireKeytar = () => require("@zowe/secrets-for-zowe-sdk").keyring;
  const profInfo = new ProfileInfo("zowe", {
    credMgrOverride: ProfileCredentials.defaultCredMgrWithKeytar(requireKeytar),
  });

Note: ProfileCredentials is a class that can be imported from the Imperative SDK like ProfileInfo.

This change was made to support other credential managers like the CLI plugin and VS Code extension for Kubernetes Secrets.
