Can't have names with uppercase letters

[jessjaco]

This works:

kbatch job submit --name=list-files --command='["ls", "-lh"]' --image=alpine

but any name with uppercase letters gives an error. For example:
kbatch job submit --name=List-files --command='["ls", "-lh"]' --image=alpine

gives

Underscores appear to have the save problem

[jessjaco]

Get same problem when passing args that are numbers (quoting them works)

[jbusecke]

Just ran into the same issue here. Is there a way we wan replace incompatible characters automatically or raise a more user friendly error message?
