[SCRIPT ONLY] Add logic to check for SPI and AS pull requests

Add logic to check for SPI and AS pull requests

i.e. including jbosstm/jboss-as#100 in the PR description

[marcosgopen]

Putting the Hold label as some variables are not defined

@marcosgopen - I think the PULL_DESCRIPTION_BODY is possibly reset due to

lra/scripts/hudson/narayana.sh

Line 174 in 5dc976d

PULL_DESCRIPTION_BODY=""

You can find this in the action:

++ echo
++ awk -F pull '{ print $2 }'
++ awk -F / '{ print $2 }'
+ PULL_NUMBER=
+ '[' '' '!=' '' ']'
+ PULL_DESCRIPTION=
+ PULL_DESCRIPTION_BODY=
+ init_test_options

Not sure if that method should be much altered as we may not need a lot of it but maybe that line needs to be altered so it doesn't empty the description passed in?
