[ZEPPELIN-2659] Let WebEnvironment initialize SecurityManager.
### What is this PR for?
This commit disables generating a Shiro `SecurityManager` from the
`IniSecurityManagerFactory`, and instead let's the `WebEnvironment` instantiate
the `SecurityManager`. The `initParameter` "staticSecurityManagerEnabled"
ensures this `SecurityManager` is set and available for use.
Overall, this prevents the double parsing of `shiro.ini`, which can cause
double instantiation. This is particularly thorny with things like EHCache,
which need uniquely named caches, and will throw an exception if a cache with
the same name already exists.
### What type of PR is it?
[Bug Fix ]
### Todos
### What is the Jira issue?
[ZEPPELIN-2659](https://issues.apache.org/jira/browse/ZEPPELIN-2659)
### How should this be tested?
- Enable Shiro by copying the shiro.ini.template to shiro.ini. Attempt
logging in as a user.
- Enable WebSessions and EHCache by adding the following lines to the
`[main]` section of shiro.ini, and attempt logging in.
```
[main]
...
sessionManager = org.apache.shiro.web.session.mgt.DefaultWebSessionManager
securityManager.sessionManager = $sessionManager
sessionDAO = org.apache.shiro.session.mgt.eis.EnterpriseCacheSessionDAO
securityManager.sessionManager.sessionDAO = $sessionDAO
cacheManager = org.apache.shiro.cache.ehcache.EhCacheManager
securityManager.cacheManager = $cacheManager
```
