Instead of getting (deleted and untracked files):
```
$ git status
# On branch master
# Your branch is ahead of 'origin/master' by 20 commits.
#
# Changes not staged for commit:
# (use "git add/rm <file>..." to update what will be committed)
# (use "git checkout -- <file>..." to discard changes in working directory)
#
# deleted: cdb_dataservices_server--0.20.0--0.21.0.sql
# deleted: cdb_dataservices_server--0.21.0--0.20.0.sql
# deleted: cdb_dataservices_server--0.21.0.sql
# modified: cdb_dataservices_server.control
#
# Untracked files:
# (use "git add <file>..." to include in what will be committed)
#
# cdb_dataservices_server--0.21.0--0.22.0.sql
# cdb_dataservices_server--0.22.0--0.21.0.sql
# cdb_dataservices_server--0.22.0.sql
# old_versions/cdb_dataservices_server--0.20.0--0.21.0.sql
# old_versions/cdb_dataservices_server--0.21.0--0.20.0.sql
# old_versions/cdb_dataservices_server--0.21.0.sql
no changes added to commit (use "git add" and/or "git commit -a")
```
you'd get something like:
```
$ git status
# On branch master
# Your branch is ahead of 'origin/master' by 20 commits.
#
# Changes to be committed:
# (use "git reset HEAD <file>..." to unstage)
#
# renamed: cdb_dataservices_server--0.20.0--0.21.0.sql -> old_versions/cdb_dataservices_server--0.20.0--0.21.0.sql
# renamed: cdb_dataservices_server--0.21.0--0.20.0.sql -> old_versions/cdb_dataservices_server--0.21.0--0.20.0.sql
# renamed: cdb_dataservices_server--0.21.0.sql -> old_versions/cdb_dataservices_server--0.21.0.sql
#
# Changes not staged for commit:
# (use "git add <file>..." to update what will be committed)
# (use "git checkout -- <file>..." to discard changes in working directory)
#
# modified: cdb_dataservices_server.control
#
# Untracked files:
# (use "git add <file>..." to include in what will be committed)
#
# cdb_dataservices_server--0.21.0--0.22.0.sql
# cdb_dataservices_server--0.22.0--0.21.0.sql
# cdb_dataservices_server--0.22.0.sql
```
which is nicer IMHO.
Found via unit test:

timedelta microseconds is just the microseconds part of the timedelta
object not the elapsed time in microseconds.
I've change to use the total_seconds method to get all the elapsed time
in seconds and transform to miliseconds.
The number of retries was being passed as the pool size parameter.
This is corrected but number of retries changed to 1 to maintain previous behaviour.
