Topic/change treatment backend

[ryan-preble]

Description

• adds ontologies for experiment treatments and composed experiment treatments
• adds script for converting treatment projects to treatment cvterms and storing entries on phenotype table
• adds server config keys (allow_trait_edits and allow_treatment_edits) that enable creation/modification/deletion of trait and treatment cvterms respectively
• adds trait and treatment designer pages, accessible to curators on sites with those features enabled
• adds field management regimes as a projectprop, accessible from trial detail page
• adds treatments and field management regimes to label designer
• adds treatments to field map viewer
• updates splitplot trial design to use treatment ontology
• updates treatments on trial upload to require trait-style identifiers
• adds treatment upload to experimental design section of trial detail page
• treatments are inherited by substocks (plot->subplot->plant->tissue sample) on treatment upload or on substock creation
• adds treatments as a group-by option on phenotype summary statistics
• adds treatment search page
• adds treatment composition page

Important things to test:

• is is possible to upload treatments that are not successfully inherited by child stocks? (the answer should be no)
• is it possible to create substocks in such a way that they do not inherit the treatments of their parents? (the answer should be no)
• does the treatment conversion dbpatch/script work on reasonably large datasets?
• do treatments work as expected on trial upload? If uploading trials and adding plants, do these plants inherit treatments as expected?
