Be more verbose when action start or connecting

[daveteu]

Description

Currently it is not being verbose enough about actions being taken, e.g. preparing files, connecting, listing files etc.

Actual behavior

e.g. When you click on deploy, there will be a long period of silence. (I assume it is preparing the files) then you have to wait for the pop up to know whether deploy started, or whether you clicked deploy on the right target.

Expected behavior

It should display "Preparing Files", or "Preparing to deploy to ${host}" so we know something is happening and whether we have correctly selected the target.

Adittional Comment

Since this is a deploy plugin, it should be rated as "mission critical" to show everything that is happening between vscode, vscode-deploy-reloaded and the target server.

Thanks for the awesome plugin, so much potential!
