Unable to install tendrl-ui alone without installing tendrl-api

[TimothyAsirJeyasing]

tendrl-UI should able to access tendrl-api from any machine where its installed separately.

Currently tendrl-ui depends on tendrl-api-httpd which does apache host ssl configuration and does the proxy configuration for forwarding requests of /api/ to tendrl-api application.
tendrl-api-httpd depends on tendrl-api.

Issue:-
tendrl-ui -> tendrl-api-httpd -> tendrl-api
Due to this chain of dependency one has to install tendrl-ui, tendrl-api and tendrl-api-httpd into the same machine. This break the usage of installing tendrl-api in different machine.

Remove tendrl-api dependency for tendrl-ui and fix the required changes:-
This issue should be resolved by removing the dependency of tendrl-api from tendrl-api-httpd and should handle the required changes in the configuration. Currently the sample / default configuration has the local host ip with the port no (for ex:- 127.0.0.1:9292). This should be the server ip where api is installed.
