term total nitrogen concentration (tot_nitro) is water specific, should be general

[mslarae13]

Describe the bug A clear and concise description of what the bug is.

The description of tot_nitro is : Total nitrogen concentration of water samples, calculated by: total nitrogen = total dissolved nitrogen + particulate nitrogen. Can also be measured without filtering, reported as nitrogen

The specification of water is limiting, you can have total N on all samples

this is used in extension

• HydrocarbonResourcesCores
• HydrocarbonResourcesFluidsSwabs
• WastewaterSludge
• Water

To Reproduce Steps to reproduce the behavior:

1. Go to https://genomicsstandardsconsortium.github.io/mixs/0000102/

Expected behavior A clear and concise description of what you expected to happen.

Terms definitions will be general, not environment specific and slot usage can be added for specific environments

[mslarae13]

Actually, it looks like a separate slot was made to be less water specific... see https://genomicsstandardsconsortium.github.io/mixs/0000530/

I recommend deprecating tot_nitro and using tot_nitro_content

will complete when deprecation protocol is in place
