What does this MR do and why?

The purpose of this MR is to permit to set variable of type file with a content of more than 10k characters. The 10k characters limit should only apply to "environment variable" variables while "file" variables can contain up to 5M characters

(Here k stands for 1 000 and M for 1 000 000).

The implementation encompass:

• modifying instance_variable validators to have different maximum length according the variable type
• enforcing the limit through a database constraint. The 5M limit correspond to a very specific value once the file content is encrypted. The test should fail if the encryption mechanism happens to be modified.
