resulttool: enable merge, store, report and regression analysis

OEQA outputs test results into json files and these files were
archived by Autobuilder during QA releases. Example: each oe-selftest
run by Autobuilder for different host distro generate a
testresults.json file.

These scripts were developed as a test result tools to manage
these testresults.json file.

Using the "store" operation, user can store multiple testresults.json
files as well as the pre-configured directories used to hold those files.

Using the "merge" operation, user can merge multiple testresults.json
files to a target file.

Using the "report" operation, user can view the test result summary
for all available testresults.json files inside a ordinary directory
or a git repository.

Using the "regression-file" operation, user can perform regression
analysis on testresults.json files specified. Using the "regression-dir"
and "regression-git" operations, user can perform regression analysis
on directory and git accordingly.

These resulttool operations expect the testresults.json file to use
the json format below.
{
    "<testresult_1>": {
        "configuration": {
            "<config_name_1>": "<config_value_1>",
            "<config_name_2>": "<config_value_2>",
            ...
            "<config_name_n>": "<config_value_n>",
        },
        "result": {
            "<testcase_namespace_1>": {
                "status": "<PASSED or FAILED or ERROR or SKIPPED>",
                "log": "<failure or error logging>"
            },
            "<testcase_namespace_2>": {
                "status": "<PASSED or FAILED or ERROR or SKIPPED>",
                "log": "<failure or error logging>"
            },
            ...

                "log": "<failure or error logging>"
            },
        }
    },
    ...
    "<testresult_n>": {
        "configuration": {
            "<config_name_1>": "<config_value_1>",
            "<config_name_2>": "<config_value_2>",
            ...
            "<config_name_n>": "<config_value_n>",
        },
        "result": {
            "<testcase_namespace_1>": {
                "status": "<PASSED or FAILED or ERROR or SKIPPED>",
                "log": "<failure or error logging>"
            },
            "<testcase_namespace_2>": {
                "status": "<PASSED or FAILED or ERROR or SKIPPED>",
                "log": "<failure or error logging>"
            },
            ...
            "<testcase_namespace_n>": {
                "status": "<PASSED or FAILED or ERROR or SKIPPED>",
                "log": "<failure or error logging>"
            },
        }
    },
}

To use these scripts, first source oe environment, then run the
entry point script to look for help.
    $ resulttool

To store test result from oeqa automated tests, execute the below
    $ resulttool store <source_dir> <git_branch>

To merge multiple testresults.json files, execute the below
    $ resulttool merge <base_result_file> <target_result_file>

To report test report, execute the below
    $ resulttool report <source_dir>

To perform regression file analysis, execute the below
    $ resulttool regression-file <base_result_file> <target_result_file>

To perform regression dir analysis, execute the below
    $ resulttool regression-dir <base_result_dir> <target_result_dir>

To perform regression git analysis, execute the below
    $ resulttool regression-git <source_dir> <base_branch> <target_branch>
