TLS cipher setting on channel gets overridden

[michaelelleby]

Usage document describes building a customer image and adding a file 20-config.mqsc to allow customizing queue manager configuration at startup.
If I try to set the SSL cipher on the channel DEV.APP.SVRCONN in 20-config.mqsc it will get overridden by 20-dev-tls.mqsc.tpl forcing the SSL cipher to be ANY_TLS12_OR_HIGHER

Two solutions:

• Rename 20-dev-tls.mqsc.tpl to 15-dev-tls.mqsc.tpl to allow user-generated MQSC script to take precedence.
• Update documentation to suggest naming the file 25-config.mqsc to allow user-generated MQSC script to take precedence.
