Bug 1344813 - Only start as many web servers as required, r=jmaher,pyang,erahm.

Bug 1344813 - remove template urls from awsy, r=jmaher,pyang,erahm.

Bug 1344813 - Implement AWSY as a marionette-based mach command, r=jmaher,pyang,erahm. usage: mach [global arguments] awsy-test [command arguments] mach awsy-test runs the in-tree version of the Are We Slim Yet (AWSY) tests. awsy-test is implemented as a marionette test and marionette test arguments also apply although they are not necessary since reasonable defaults will be chosen. The AWSY specific arguments can be found in the Command Arguments for AWSY section below. awsy-test will automatically download the tp5n.zip talos pageset from tooltool and install it under topobjdir/_tests/awsy/html. You can specify your own page set by specifying --web-root and --page-manifest. The results of the test will be placed in the results directory specified by the --results argument. Command Arguments for AWSY: --web-root WEBROOTDIR Path to web server root directory. If not specified, defaults to topobjdir/_tests/awsy/html. --page-manifest PAGEMANIFEST Path to page manifest text file containing a list of urls to test. The urls must be served from localhost. If not specified, defaults to page_load_test/tp5b/tp5n.manifest under the web root. --results RESULTSDIR Path to results directory. If not specified, defaults to the parent directory of the web root. --quick Set --entities=3, --iterations=1, --per-tab-pause=1, --settle-wait-time=1 for a quick test. Overrides any explicit argument settings. --entities ENTITIES Number of urls to load. Defaults to the total number of urls. --max-tabs MAXTABS Maximum number of tabs to open. Defaults to 30. --iterations ITERATIONS Number of times to run through the test suite. Defaults to 5. --per-tab-pause PERTABPAUSE Seconds to wait in between opening tabs. Defaults to 10. --settle-wait-time SETTLEWAITTIME Seconds to wait for things to settled down. Defaults to 30.

Bug 1344813 - prepare awsy for mach command, r=jmaher,pyang. * parse_about_memory.py - remove extraneous data variable. * test_memory_usage.py - get webRootDir, resultsDir from testvars to support mach command. - standardize directories. - catch exceptions thrown by marionette when closing tabs. * awsy_script.py - change to use webRootDir, resultsDir and to pass to test_memory_usage.py in additional testvars.json file. - standardize directories. - set strict=False in StructuredOutputParser in order to prevent ascii encoding errors due to marionette loading csdn.net and outputing non-ascii to stdout.
