Steps to Reproduce:

1. Deploy elasticsearch
2. Copy container IP (because internal-cluster-dns doesn't work with vanilla Rancher 2.x)
3. Enable elasticsearch logging
4. Paste elasticsearch container IP
5. View elasticsearch indexes

Results:

When setting up Rancher logging to Elasticsearch, it says the generated index will be innovations_Default-2018-10-02, however, the actual index created in elasticsearch is innovations_default-2018-10-02

The index is all lower-cased

Version: master 2.2 (12/3/18)
Confirmed fixed. elasticsearch indicies can only be lowercase. This change fixes the UI so that if you have capital letters in your proposed index name it shows as lowercase now in the UI. I confirmed this fix in the UI and also hooked it up to elasticsearch to confirm it is working as expected.
