Respect MaxRamPercentage in container

Currently if user specifies `MaxRamPercentage` without specifying `Xmx`,
Alluxio still gives a defualt `Xmx` which will override the
`MaxRamPercentage` because of priority. Fix this by if user specifies
`MaxRamPercentage` we don't give a default `Xmx`.

First step of solving #10083
Replace #15819
