Files with a conf extension are run by the scylla_prepare on the AMI.
The scylla-housekeeping configuration file is not a bash script and
should not be run.
This patch changes its extension to cfg which is more python like.

The housekeeping.conf is a configuration file for scylla-housekeeping.
By default it will be included in the rpm and state that the
check-version would be run.
If the file is missing, or if check-version is set to false, the check
version operation will not be performed.

This patch adds the prometheus API it adds the proto library to the
compilation, adds an optional configuration parameter to change the
prometheus listening port and start the prometheus API in main.
To disable the prometheus API, set its listening port to 0.

Fixes#614
* Use warning threshold from config
* Don't throw exceptions. We're only supposed to warn.
* Try to actually estimate mutation data payload size, not
number of mutations.
Describe scylla version of option.
Note, for test usage, the below should be workable:
server_encryption_options:
internode_encryption: all
certificate: seastar/tests/test.crt
truststore: seastar/tests/catest.pem
keyfile: seastar/tests/test.key
Since the seastar test suite contains a snakeoil cert + trust
combo
This patch substitutes uint64_t for uint32_t as the type for
commitlog_total_space_in_mb. Moving to 64 is not strictly needed, since even a
signed 32-bit type would allow us to easily handle 2TB. But since we store that
in the commitlog as a 64-bit value, let's match it.
Moving from unsigned to signed, however, allow us to represent negative
numbers. With that in place, we can change the semantics of the value
slightly, so to allow a negative number to mean "all memory".
The reason behind this, is that the default value "8GB", is an artifact of the
JVM. We don't need that, and in many-shards configuration, each shard flushes
the commitlog way too often, since 8GB / many_shards = small_number.
8GB also happens to be a popular heap size for C* in the JVM. For us, we would
like to equate that (at least) with the amount of memory. The problem is how to
do that without introducing new options or changing the semantics of existing
options too radically.
The proposed solution will allow us to still parse C* yaml files, since those
will always have positive numbers, while introducing our own defaults.

1. Supported parameters
2. Not supported parameters: saved for future use or backward compatibility
