HDDS-1788. Add kerberos support to Ozone Recon
URL: https://github.com/apache/hadoop/pull/1201
Recon fails to come up in a secure cluster with the following error:
```
Failed startup of context
o.e.j.w.WebAppContext@2009f9b0{/,file:///tmp/jetty-0.0.0.0-9888-recon-_-any-2565178148822292652.dir/webapp/,UNAVAILABLE}{/recon}
javax.servlet.ServletException: javax.servlet.ServletException: Principal not
defined in configuration at
org.apache.hadoop.security.authentication.server.KerberosAuthenticationHandler.init(KerberosAuthenticationHandler.java:188)
at
```
This patch addresses this issue and enables Recon to come up in clusters
secured by kerberos. I have manually tested the patch by creating the recon jar
and replacing an old jar in a live secure CM deployed cluster and verified that
Recon starts successfully and is able to login successfully with the kerberos
ticket. Also updated ozonesecure docker-compose file to add recon and verified
that recon is able to come up successfully. This patch also fixes various typos
found in other parts of the source code not related to the title of this JIRA.
