Issue:
[feature] show uploaded files size in `conan upload`
<!-- What is your suggestion? Please be as specific as possible! -->
It would be very convenient to provide the size of files which will be upload to specific remote via `conan upload ...` in diagnostic purposes, e.g. sometimes artifacts could be very large and CI could refuse its uploading, see e.g. [this StackOverflow question](https://stackoverflow.com/questions/64329087/gitlab-self-hosted-error-uploading-artifacts-as-archive-to-coordinator-to) as example of related CI error. With this change CI administrators could adjust the file limit at CI without trial and error changing of CI configs.

Discussion:
It is relatively straightforward to just check the files in the Conan cache in case the upload failed, so not a high priority. We might add it to the output in Conan 2.0, depends on how cluttered the output looks, might be added or not, we will see.
@memsharded was the decision to add it or to not? Should this ticket be closed?
Neither, a decision was not taken. This kind of small ux details haven't been considered yet. I am fine with adding the info before/during upload of big files only (all files would be very noisy)
