When using metadata containing _, the behavior is different from aws-s3.

s3cmd put ~/1m s3://mytest --add-header 'x-amz-meta-key_1: value_1'
s3cmd get --debug s3://mytest/1m

rgw result:

{'headers': {
             ...
             'x-amz-meta-key6-1': 'value_1',
             ...

aws-s3 result:

{'headers': {
             ...
             'x-amz-meta-key6_1': 'value_1',
             ...

The second case is

s3cmd put ~/1m s3://mytest --add-header 'x_amz_meta_key_1: value_1'
s3cmd get --debug s3://mytest/1m

rgw result:

{'headers': {
             ...
             'x-amz-meta-key6-1': 'value_1',
             ...

aws-s3 result:

{'headers': {
             ...
