Subject: Raise max header size to accommodate large tokens.

The max header is exceeded in the following scenario
- Auth tokens built with a keystone v3 API catalog
- A catalog with approximately 8 or more endpoints defined

Specifically, when heat is enabled in tempest gating, the following
tests are failing:
- tempest.api.compute.test_auth_token.AuthTokenTestJSON.test_v3_token
- tempest.api.compute.test_auth_token.AuthTokenTestXML.test_v3_token

An equivalent fix will be required for all projects which use
eventlet.wsgi.

Fixes bug: #1190149
