Abstract:  Disable RC4-based TLS ciphers by default in IBM HTTP Server

Description/symptom of problem:  
PI34229 resolves the following problem:

ERROR DESCRIPTION:
When SSL is enabled with 'SSLEnable', IBM HTTP Server includes 
RC4-based ciphers in its default ciphers.

LOCAL FIX:                                                      

PROBLEM SUMMARY:
RC4 is now considered 'weak', so RC4-based ciphers should not be
included in the default list.

PROBLEM CONCLUSION:
RC4 was removed from the set of default ciphers in V7R0 and later.

- 7.0.0.39 
- 8.0.0.11 
- 8.5.5.6
