Validate provider code is uppercase

[inulty-dfe]

Context

We had a support issue some time back where someone created a provider and one or more of the letters were entered downcase. The providers courses would not load on find.

Changes proposed in this pull request

Validate that when creating a new Provider that their provider code is the correct format:

• 3 characters long
• At least one number
• the other two characters can be numbers or letters.
• Any order

Add normalization to the provider_code column so that any input is upcased.

Guidance to review

Provide code length	Doesn't validate upcase	Validates invalid format

Checklist

• I have moved hard-coded strings to locale files.
• I have removed the usage of data-qa attributes in HTML files and updated the corresponding tests.

Could we normalise the uppercase-ness instead of validating it?

Yeah, this is probably a good idea. Are you recommending we spend time doing this?
