Wip writeback throttling for cache tiering
This patch is to do write back throttling for cache tiering, which is similar to what the Linux kernel does for page cache write back. A paramter 'cache_target_dirty_high_ratio' (default 0.6) is introduced as the high speed flushing threshold, while leave the 'cache_target_dirty_ratio' (default 0.4) to represent the low speed threshold. The flush speed is controlled by limiting the parallelism of flushing. The maximum parallelism under low speed is half of the parallelism under high speed. If there is at least one PG such that the dirty ratio beyond the high threshold, full speed mode is entered; If there is no PG such that dirty ratio beyond the low threshold, idle mode is entered; In other cases, slow speed mode is entered.

When updating submodules, always checkout even if the HEAD is the
desired commit hash (update --force) to avoid the following:
* a directory gmock exists in hammer
* a submodule gmock replaces the directory gmock in master
* checkout master + submodule update : gmock/.git is created
* checkout hammer : the gmock directory still contains the .git from
master because it did not exist at the time and checkout won't
remove untracked directories
* checkout master + submodule update : git rev-parse HEAD is
at the desired commit although the content of the gmock directory
is from hammer

Encapsulate the compilation steps (install dependencies, autogen.sh,
configure, make check) in the run-make-check.sh script. Update the
developer documentation to point to this script instead of multiple
steps.
It is intended as a tool to help new developer make sure their patch is
sane, it focuses on efficiency (runs make check in parallel if possible)
and coverage (enables docker based tests if possible).

The prototype of the init functions of erasure coded plugins is changed
from
int __erasure_code_init(char *plugin_name)
to
int __erasure_code_init(char *plugin_name, char *directory)
The jerasure plugin will find optimized variants in this directory and
load them. The load() and preload() functions of
ErasureCodePluginRegistry only use a directory instead of a more generic
parameters map. The parameters map was only used for the directory entry
anyway.
