Fix Zeppelin web build

[anthonycorbacho]

This PR is about simplifying the pom (by updating the frontend-maven-plugin plugin) plus doesn't reinstall node, npm and bower components for every build.

Fix also the imagemin error lib64/libc.so.6: version GLIBC_2.XX' not found on Linux

New version of eirslett/frontend-maven-plugin implements running bower and running grunt so this PR take advantage of it which simplifies pom.xml
Looks great to me!

[anthonycorbacho]

For the issue #295, the root pom is a mess and it is really hard to understand what is going on there and the pluginManagement somehow trigger the webapp to be build 2 time.
The only way I found is to comment out the

 <parent>
    <artifactId>zeppelin</artifactId>
    <groupId>com.nflabs.zeppelin</groupId>
    <version>0.5.0-SNAPSHOT</version>
  </parent>

For me it is totally fine because

• Zeppelin web app is self contain and doest require any dependency from the parent
• Zeppelin web already have a checkstyle (JSHints)

Now the webapp only need ~54s to build.....

Any advice or cleaner way to solve this issue?

[anthonycorbacho]

Well I think this PR is ready to go.
I tested it againts OSX, centOS 6.5 and Ubuntu and compilation worked fine.
Also updated the readme file.

@Leemoonsoo can you take a look and tell me whats bother you?

Can someone review this PR?

[Leemoonsoo]

Great. It works perfectly for me, but let me test little bit more with different conditions.

[anthonycorbacho]

@Leemoonsoo sure.

[corneadoug]

Tested on Mac OSX after git clean and bower/node cache cleaned, worked well even though I don't get the same compilation speed (2:35:271 for me), but it is clearly faster and there is no duplicate anymore on the web part

[anthonycorbacho]

@corneadoug of course the build 'speed' will depends on your hardware :)

[Leemoonsoo]

Tested with non-root / root user. with/without build-distr. Great work! LGTM!

[anthonycorbacho]

So it is good to be merge?

[Leemoonsoo]

I think it's good to go.
