Fix the source repository links of the components.

The scm urls in the pom files pointed to the old repositories (e.g. neo4j/community).
They now point to the correct places.
fix for batch operations with https

InternalJettyServletRequest needs to return the correct value for getScheme() as it might be used in the Location header of batch responses.
Exposes RequestContextFactory from the HAGD DependencyResolver
Pull update now happens on slave startup, before allowing any transactions

There was an edge case where the slave would start up and the moment the
 constructor returns, before any update pulling has happened, a bunch of
 transactions would start and all would attempt to pull updates as part
 of initializing them. If the slave was too far behind in txs, this would
 impose a considerable load on both the slave and the master, deteriorating
 service for noticeable spans of time. Moreover, most of the data transferred
 would be thrown away, as only one tx would apply the received tx stream.
 This fix makes sure that before any transactions start the slave will
 pull updates, no matter what. This is single threaded operation so it
 won't impose any extra load.

Adds a test for the above.
Removes unneeded echo from utils script
BatchInserterImpl now uses the StoreLocker to lock access
Fixed tests and error messages
Tagging for version 1.9.1
Back to development version.
Adds toString() in MemberIsAvailable/MemberIsUnavailable
Removing implicit dependency on system clock.

Introduced the Clock interface to remove the direct dependency on System.currentTimeMillis()
Merge pull request #891 from sarmbruster/batch_ops_with_https

fix for batch operations with https
Improved Network test by using countdown latch.

Removed the horrid thread sleep in this test and replaced with a CountDownLatch with the same timeout value. Also made sure this test actually asserts that a message is both sent and received.

Also removed some unused parameters and methods.

Removed commented out code.
Renamed the test for better epressiveness.
Run databases in target directory instead of using default temp file location.
Shutdown executor with timeout instead of waiting indefinitely for futures.
Merge pull request #865 from VolkerL/fix-scm

Fix the source repository links of the components.
Fixed default path to be under target/

So that it gets properly ignored by git. It was changed to a non-target/ directory in ab735b2521142a2e003f1ba9668d551dd6eb7769
Unused imports
