Fix quantity case for ephemeral storage

Browse Source 
All resource requests parse units the same way. Ephemeral storage previously had an upper case `K` as a valid unit but the kubernetes server can not parse this value.

Similar to memory, add a statement regarding that a lowercase `m` will be accepted by the kubernetes server, but is probably an incorrect request.

Pay attention to the case of the suffixes. If you request `400m` of ephemeral-storage, this is a request
for 0.4 bytes. Someone who types that probably meant to ask for 400 mebibytes (`400Mi`)
or 400 megabytes (`400M`).
