Sampling project form error handling

[jwest60]

You will need to branch off of the scientific-sampling branch.

Currently, when you create a sampling project with missing information or if a server error occurs, the POST request fails silently (the user creating the sampling project does not know that it failed, nor why)

Here is what we want:

• The user is notified that creation failed (the error message should be different depending on whether this is a 422 or a 500 error)
• If the error response code is 422 (missing data), tell the user what information is missing
• Highlight form elements that are missing in red

• alert for alerting the alerting the user
• promises and async
• axios: error handling
• Look at code examples in our codebase.
