Actual results:
 
result for step3:
error: ReplicationController "database-1" is invalid: [spec.template.spec.containers[0].env[6].name: invalid value '1230#%0%', Details: must be a C identifier (matching regex [A-Za-z_][A-Za-z0-9_]*): e.g. "my_name" or "MyName", spec.template.spec.containers[0].env[6].name: invalid value '1230#%0%', Details: must be a C identifier (matching regex [A-Za-z_][A-Za-z0-9_]*): e.g. "my_name" or "MyName"]

result for step4:
The Pod "database-1-wwts3" is invalid.

see 'oc label -h' for help.

Expected results:
result for step3:
Error information should be displayed only once

result for step4:
Error information should be displayed only once

result for step5:
Should promote error information about invalid value "qyuertr124%$###$%"and give suggestion about what value is valid, just as the web console does [a valid label value is an alphanumberic(a-z,and 0-9)string,with a maximum length of 63 characters with the '-'character allowed anywhere except for the first and last character]
