- add PcaAdminPermission to allow managing all pca services
 - Allow node token modification for standard users: standard users can add/remove a token when they are already running a task on the node. Only admin users can do this operation outside of a task execution.

Empty lines was created by log4j messages already containing end of lines characters.
This fix makes sure that each log message terminates with a single end-of-line (in Log4JTaskLogs, thanks to StringUtils.stripEnd).
It also makes sure that no blank lines are added between individual task logs (changes in SchedulerStateRest).

 - include library to download remote server certificate as a keystore
 - some small modifications regarding property paths resolution

To fix an observed thread leak due to RMListenerProxy hanging on getMonitoring().removeRMEventListener() this change aims at rationalizing and adding timeouts to the linked requests.

Additionally, add a Thread.setDefaultUncaughtExceptionHandler to properly log uncaught exceptions in Scheduler.log

 - add missing consolidation functions in rrdb files
 - remove unsupported functions from the doc

 - function default value is AVERAGE. Other values such as MIN, MAX, TOTAL can be used (based on the rrd4j api)
 - improve resource manager rest api

- After refactoring and creating of the rest-api modile, miredot documentation was mostly empty due to declaration of methods inside rest-api interfaces
- Refactor RestDataspaceImpl similarly as other interfaces
- Improve Rest dataspace documentation
- upgrade miredot plugin version

* Adding ossindex plugin in gradle
* Enforcing security fixes of several dependencies

This new regexp does not split on spaces characters, but only trim around delimiters

* Task Filter status

* Fix TaskDBUtils

* Fix SchedulerDBManagerTest

* Fix moar tests

* Fabiens comments

* Typo and correct permission check

 - Usage : server_address/rest/common/permissions/portals?portals=studio&portals=scheduler&portals=rm

 - Create new rest component "common/" with CommonInterface definition and CommonRest implementation
 - CommonInterface defines the method permissions/portals/{portal} to check portal authorization
 - portal authorization is implemented as JaaS PortalAccessPermission
 - cleanup some code related to sessions in rest server
 - RMCore check authorization in ImmediateService requests
 - cleanup authorizations in jaas policy, notably for "guest"

- Avoid duplicating empty values or default node source

Also:
 - skip model fetching in PA:MODEL_FROM_URL if the url contains variables
 - minor constants refactoring
 - apply comments
 - use http downloader to handle http urls

* Fix getState and getInfras/getPolicies

* Proper GETers for resteasy

* Fix topology

* Better name

* create separate rm-api module

* create RMRestClient which uses Resteasy builder to create proxy of RMRestInterface

* create RMNodeClient which handles connection to RM and uses RMRestClient

* bind 'rmapi' to instance of RMNodeClient

* Add Javadocs to RMNodeClient

* Add single test, in SchedulerClientTest

* Add setNodeTokens

* Fix unit test

* Update db with new tokens

Add REST endpoint and RM JAVA API that allows to dynamically changed tokens of the RMNode.

POST: example.com/rest/rm/node (headers: sessionid, nodeurl, token) calls RMCore::addNodeToken

DELETE: example.com/rest/rm/node (headers: sessionid, nodeurl, token) calls RMCore::removeNodeToken
 

* Remove redundant annotations

* Wrap/unwrap exceptions

The new endpoint that returns RMNodeHistory items which are inside the given window.
Group by node source name, then hostname, then node name.
Sort by start time.
If start time before window then set it to window start.
if end time after window (or zero) then set it to window end.

* feat [PA:CREDENTIAL]: add workflow variable type PA:CREDENTIAL.

* feat [PA:CREDENTIAL]: pass scheduler instance when submit workflow and require scheduler rest interface to pass sessionId, so that CredentialValidator can check whether paramValue exist in third-party credentials.

* Add new endpoint getNodesMBeanHistory
