Specify run order

[amamiya-yuuko-1225]

This PR is a new implement for PR#348.

The changes in this pull request enable Surefire to run test classes and test methods in any order specified by a newly added <runOrder> (testorder). Namely, the changes include

• A new <runOrder> called testorder that would make Surefire run test classes and test methods in the order specified by <test>. Regex and include/exclude are supported as is the case for other runOrders
• Tests for the newly added features

The newly added testorder <runOrder> is supported for JUnit 3 and JUnit 4 tests.

Moreover, I have also implement a preliminary support for JUnit5, but I need some help to make it better. For this reason, I created another PR to show that change. Looking forward to discuss it with you developers about this issue.

Simple (no regex) example using Http-Request:

mvn test -Dsurefire.runOrder=testorder \
-Dtest=com.github.kevinsawicki.http.HttpRequestTest#getUrlEncodedWithPercent,\
com.github.kevinsawicki.http.HttpRequestTest#uploadProgressSendReader,\
com.github.kevinsawicki.http.HttpRequestTest#malformedStringUrlCause,\
com.github.kevinsawicki.http.EncodeTest#encode

Output from Maven should say that the test class HttpRequestTest ran before EncodeTest

The file HttpRequestTest.xml (http-request/lib/target/surefire-reports/TEST-com.github.kevinsawicki.http.HttpRequestTest.xml) should say

<testcase name="getUrlEncodedWithPercent"...>
<testcase name="uploadProgressSendReader"...>
<testcase name="malformedStringUrlCause...>

Regex example using Http-Request:

mvn test -Dsurefire.runOrder=testorder \
-Dtest=com.github.kevinsawicki.http.EncodeTest*,\
com.github.kevinsawicki.http.HttpRequestTest#getUrl*

Output from Maven should say

Tests run: 2 … in 
com.github.kevinsawicki.http.EncodeTest
Tests run: 4 … in
com.github.kevinsawicki.http.HttpRequestTest

The file HttpRequestTest.xml (http-request/lib/target/surefire-reports/TEST-com.github.kevinsawicki.http.HttpRequestTest.xml) should say

<testcase name=”getUrlEncodedWithPercent”...>
<testcase name="getUrlEncodedWithSpace"...>
<testcase name="getUrlEncodedWithUnicode”...>
<testcase name="getUrlEmpty”...>

Include/Exclude example using Http-Request:

mvn test -Dsurefire.runOrder=testorder \
-Dtest=com.github.kevinsawicki.http.HttpRequestTest#getUrl*,\
\!com.github.kevinsawicki.http.HttpRequestTest#getUrlEmpty

Output from Maven should say
Tests run: 3 … in

com.github.kevinsawicki.http.HttpRequestTest

The file HttpRequestTest.xml (http-request/lib/target/surefire-reports/TEST-com.github.kevinsawicki.http.HttpRequestTest.xml) should say

<testcase name=”getUrlEncodedWithPercent”...>
<testcase name="getUrlEncodedWithSpace"...>
<testcase name="getUrlEncodedWithUnicode”...>
