The script was embedded in the playbook, which leads to some pain with regard to editing and reviewing as well as manual testing. The disadvantage of doing this is that it can make jobs somewhat less portable between projects, but in this case that's not really an issue. There are further improvements that can made to remove duplication between the nested and non-nested versions of these jobs. This change will make it easier for those changes to be made as people have time. Change-Id: Ia6795ef15a03429c19e66ed6d297f62da72cc052changes/44/666544/1

# Do some performance related information gathering for placement. |
||||
EXPLANATION=" |
||||
This output combines output from placeload with timing information |
||||
gathered via curl. The placeload output is the current maximum |
||||
microversion of placement followed by an encoded representation of |
||||
what it has done. Lowercase 'r', 'i', 'a', and 't' indicate successful |
||||
creation of a resource provider and setting inventory, aggregates, and |
||||
traits on that resource provider. |
||||
|
||||
If there are upper case versions of any of those letters, a failure |
||||
happened for a single request. The letter will be followed by the |
||||
HTTP status code and the resource provider uuid. These can be used |
||||
to find the relevant entry in logs/screen-placement-api.txt.gz. |
||||
|
||||
Note that placeload does not exit with an error code when this |
||||
happens. It merely reports and moves on. Under correct circumstances |
||||
the right output is a long string of 4000 characters containing |
||||
'r', 'i', 'a', 't' in random order (because async). |
||||
|
||||
After that are three aggregate uuids, timing information for the |
||||
placeload run, and then timing information for two identical curl |
||||
requests for allocation candidates. |
||||
|
||||
If no timed requests are present it means that the expected number |
||||
of resource providers were not created. At this time, only resource |
||||
providers are counted, not whether they have the correct inventory, |
||||
aggregates, or traits. |
