Description of problem:
Registering a client server via bootstrap.sh to a Satellite 5.4.1 or 5.5.0 server fails because of an SSL certificate validation error.

The problem is on line 195 of bootstrap.sh. The rpm command is used to fetch the Satellite Certificate Authority RPM file. The rpm command uses curl to fetch the file and by default curl verifies the SSL certificate, but because the client server does not already have the Satellite Certificate Authority installed, the file download will fail because of a SSL certificate validation error. Using the rpm command bypasses the logic done on lines 115 - 135 to prevent this problem.

Version-Release number of selected component (if applicable):
(Satellite 5.4.1) spacewalk-certs-tools.noarch        1.7.3-3.el6sat
(Satellite 5.5.0) spacewalk-certs-tools.noarch        1.7.3-4.el6sat 

How reproducible:
Always.

Steps to Reproduce:
1. On the Satellite server, generate a new bootstrap.sh by executing "rhn-bootstrap" as root. Make the necessary changes to the new bootstrap.sh in /var/www/html/pub/bootstrap: Comment out "exit 1", and set ACTIVATION_KEYS=.
2. On the client server, wget the new bootstrap.sh: wget http://satellite.foo.net/pub/bootstrap/bootstrap.sh
3. On the client server, execute the bootstrap.sh

curl: (60) Peer certificate cannot be authenticated with known CA certificates
More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.
