### Set legal hold on an object

PutObject API allows setting legal hold using `x-amz-object-lock-legal-hold` header.

```sh
aws s3api put-object --bucket testbucket --key legalhold --object-lock-legal-hold-status ON --body /etc/issue
```

		{
			metadata: map[string]string{
				"x-amz-object-lock-legal-hold": "on",
			},
			expected: ObjectLegalHold{Status: LegalHoldOn},
		},
		{
			metadata: map[string]string{
				"x-amz-object-lock-legal-hold": "off",
			},
			expected: ObjectLegalHold{Status: LegalHoldOff},
		},
		{
			metadata: map[string]string{
				"x-amz-object-lock-legal-hold": "X",
			},
			expected: ObjectLegalHold{Status: ""},
