allow parameters for restart effector, including children and the machine for SoftwareProcess.restart;
if this model is sensible we might apply it more widely to effectors, to allow parameters to tune behaviour.
(eg for stop, to allow controlling whether it is the machine or just the process which is stopped,
and on start, to allow forcing reinstall)
fix error where collapsed text would leave out interesting messages included with the propagation, with tests
fix failures introduced by dynamic/parametrized RESTART effector; main items are:
    * factory not calling init (deprecate EntityFactory);
    * do{Start,Stop,Restart} methods not getting invoked (deprecated, replaced by pre- and post- start overrides)
propagate entitlements as tasks are submitted, to fix failing AcmeEntitlementManagerTest
add missing @EffectorParam for policy test; also tweak the test so build completes a bit faster
allow units to be passed for `minRam` and `minDisk`
Delete http method on entities.
Rename brooklynObject.getTagSupport() to tags()
Rename entityInternal.getFeedSupport() to feeds()
Mark getRebindSupport() as @Beta

- adds comment that this code should never be called or implemented
  directly by a user, and that it may change or be deleted in
  future versions without notice.
Fix GeoscalingWebClientTest

- Adds comment to GeoscalingWebClient about trust store.
- Was failing due to certificate not in trust store. For tests,
  run with trustAll
- Also convert from groovy to java
Fix GeoscalingIntegrationTest

- it was not instantiating StubHostGeoLookup
Fix SshMachineLocationIntegrationTest

- It needs the brooklyn.properties contents for named location
  “localhost-passphrase”, so can’t just use `newManagedInstanceForTests`
Fix QpidIntegrationTest

- use correct management URL (otherwise get back 404)
Fix NnginxClusterIntegrationTest

- if use initialSize=0, then serviceUp behaves differently when
  cluster is empty. So don’t do that.
Avoid NPE in REST api deserialisation

- motivated by NPE in TaskSummary<init> for tags
remove string escaping of single quote in java (allowed for java but not for JS)
This closes #258
code review cleanup for minram / mindisk - correctly uses 1000 when converting to jclouds settings
This closes #265
