Show total count of issues found

[xrigau]

Every time I go on a boyscout mission and fix some static analysis issues I end up with the number of issues for each analysis type, but I have to configure a threshold for the total number of issues:

> Checkstyle rule violations were found (58 errors, 43 warnings). See the reports at:
- file:///Users/xrigau/development/git/novoda/some-cool-project/app/build/reports/checkstyle/main.html
> Findbugs rule violations were found (9 errors, 6 warnings). See the reports at:
- file:///Users/xrigau/development/git/novoda/some-cool-project/app/build/reports/findbugs/coolprojectStaging.html
> PMD rule violations were found (11 errors, 13 warnings). See the reports at:
- file:///Users/xrigau/development/git/novoda/some-cool-project/app/build/reports/pmd/main.html

It'd be a lot easier if it printed a line such as:

Total: 78 errors, 62 warnings

So that I can update the thresholds after every boyscoutting more easily.

This wouldn't be needed if #18 was implemented

This can be easily added independently from #18. Let's do it 👍

Regarding this, I was also thinking about merging results across sub-projects in a big Gradle project.
Imagine a project with many modules, when a tool fails the build, it is hard to detekt which module it is. And reports are separated since they run individually on all projects.

Also in such scenario, maxErrors does not make much sense individually for each submodule. It would only makes sense when maxErrors = 0 (simply because 0 x noOfModules = 0)

In past projects, I did the following to merge unitTest results. This is something provided by Gradle. I couldn't find an easy way to do the same for lint for example (i.e merging lint results from different modules)

Merging multiple unit test results:

  def testTasks = [...] // manual list of all test tasks

  task testReport(type: TestReport) {
    destinationDir = file("$buildDir/reports/allTests")
    reportOn { testTasks.collect { project.tasks.findByPath(it)*.binResultsDir } }
  }

@xrigau today is your lucky day

EXCITEMENT!

I thought you would have 0 warnings and error by now 🧌
