Add wsrep_sst_method

[rickerc]

Allow selection of wsrep_sst_method to support platforms such as Ubuntu
trusty on which the default rsync SST method will not work with Percona
XtraDB.

I have the linter set to be fairly strict at the moment. It's failing on http://puppet-lint.com/checks/variables_not_enclosed/

[rickerc]

hmm, the lines it fails on are:

$wsrep_sst_auth = "root:${galera::root_password}"

warning("wsrep_sst_method of ${galera::wsrep_sst_method} not recognized and may need authentication configured")

Those both look fine and pass local lint:

$ puppet-lint params.pp
WARNING: line has more than 80 characters on line 63
WARNING: line has more than 80 characters on line 68
WARNING: line has more than 80 characters on line 76
$

(and if I drop the brackets from 64 it then fails with
WARNING: variable not enclosed in {} on line 64
so my local puppet-lint is definitely checking that)

I wonder if Travis is somehow caching because of the amend commits? The logs look like its doing a new checkout but...

[rickerc]

Ok, that was it -- can't do an amend commit to fix a failing lint test apparently. Thanks!

(though it's more github being silly rather than Travis, apparently)

If you amend and push -f it doesn't re-launch the tests?
