[ClusterLabs] Single quotes in values for 'crm resource <rsc> param set'

[Vladislav Bogdanov]

Hi Kristoffer, all.

Could you please look why I get error when trying to update valid 
resource value (which already has single quotes inside) with the 
slightly different one by running the command in the subject?

It looks like is_value_sane() doesn't accept single quotes just because 
crmsh quotes all arguments to crm_resource with them. I need to pass a 
command-line with semicolons in one of parameters which is run with eval 
in the resource agent. Backslashed double-quoting does not work in this 
case, but single-quotes work fine.

Could that be some-how fixed?

Best,
Vladislav
