Improved _active_tasks API

Tasks are now free to set any properties they wish (as an
Erlang proplist). Different tasks can have different properties
and the status string doesn't exist anymore - instead client
applications can build it using more granular properties from
_active_tasks. Some of these properties are:

1) "progress" (an integer percentage, for all tasks)
2) "database" (for compactions and indexer tasks)
3) "design_document" (for indexer and view compaction tasks)
4) "source" and "target" (for replications)
5) "docs_read", "docs_written", "doc_write_failures",
   "missing_revs_found", "missing_revs_checked", "source_seq",
   "checkpointed_source_seq" and "continuous" for replications

Add a remsh script for each node

BugzId: 12730

Cookies now default to using ~/.erlang.cookie which is automatically
generated if it does not exist when erlang starts with a name.

There is also no longer a need to specify a name to remsh as it'll
generate a name based on the process id and set the short or long
version appropriately.

The remsh pattern is quite useful for connecting to running nodes for
debugging production issues. This adds a small script that lets users
connect quickly to a running node.
