Replace FileUtils.toByteArray() with IOUtils
The in-house implementation of FileUtils.toByteArray() appears to be a literal copy-and-paste of IOUtils.toByteArray(). This change replaces the in-house implementation with a call to IOUtils. Change-Id: Ib33b64c4c0050acb0787915dd9df190e284b8cda Signed-off-by: Gary Wu <gary.i.wu@huawei.com>
