Bug 167076

Description of problem:

Currently, yum displays the ETA for each file as it downloads and then the total
time taken to download the file when finished.  Given that the file is
downloaded, it's interesting to know, but not that useful.

What would be better would be for the time to be replaced with the cumulative
total of the download.  Giving the user some idea of how far they are through a
download.  This would be much more useful to know.

So for example, instead of this:

(1/14): kernel-devel-2.6. 100% |=========================| 4.2 MB    01:25
(2/14): spamassassin-3.1. 100% |=========================| 929 kB    00:17
(3/14): openoffice.org-wr 100% |=========================| 2.7 MB    00:56
(4/14): openoffice.org-dr 100% |=========================| 1.0 MB    00:21
(5/14): openoffice.org-co 100% |=========================|  75 MB    26:48
(6/14): openoffice.org-ma 100% |=========================| 1.3 MB    00:24
(7/14): openoffice.org-ca 100% |=========================| 6.4 MB    02:15
(8/14): openoffice.org-im 100% |=========================| 1.6 MB    00:38

yum would display this:

(1/14): kernel-devel-2.6. 100% |=========================| 4.2 MB      4.2 MB
(2/14): spamassassin-3.1. 100% |=========================| 929 kB      4.3 MB
(3/14): openoffice.org-wr 100% |=========================| 2.7 MB      7.0 MB
(4/14): openoffice.org-dr 100% |=========================| 1.0 MB      8.0 MB
(5/14): openoffice.org-co 100% |=========================|  75 MB     83.0 MB
(6/14): openoffice.org-ma 100% |=========================| 1.3 MB     84.3 MB
(7/14): openoffice.org-ca 100% |=========================| 6.4 MB     90.7 MB
(8/14): openoffice.org-im 100% |=====================    | 1.3 MB    00:38 ETA

Or even better might be to display how many MB to go (which would be a similar
process given the total download is know before yum starts.)
