HADOOP-19309: S3A CopyFromLocalFile operation fails when the source file does not contain file scheme

[shameersss1]

Description of PR

When the sourcePath does not contain any file scheme information, S3A CopyFromLocalFile operation fails. Additionally the failure is seen only when the config fs.s3a.optimized.copy.from.local.enabled is enabled (which is by default). This happens only when the local source file is given without any file scheme for example : /tmp/file.txt instead of file:///tmp/file.txt.

How was this patch tested?

Added a test case to validate the issue and the fix. Ran the testITestS3ACopyFromLocalFile in us-east-1
