Add device_config flag to change the threshold for logging log list
update failures to statsd

This will allow it easier to debug the logging logic, without needing to
hit the default threshold of 10.

Move DownloadManager.COLUMN_REASON conversion to failure reason into
CTLogger

This CL adds a new API that will convert the
DownloadManager.COLUMN_REASON into the relevant proto failure reason
enum value. The reason why it is a new API rather than reusing an
existing one is because the parameter type is the same (int), so a
separate API will keep it clearer when the DownloadManager value vs. proto enum value is directly used.

Remove CertificateTransparencyInstaller
The task of installing a new log list is now performed by the
CompatibilityVersion class.

Also, each CompatibilityVersion provides the URLs hosting the signature
and log list files. We do not store that information in the DataStore.

Add logging when signature is either not found or doesn't pass
verification

Note: InvalidKeyExceptions may be thrown for other reasons (e.g.
signature algorithm not matching), hence the addition of a new Exception
to specify when the public key is missing.

Add new APIs to DataStore to allow for int storage
The failure count for CTLogListUpdateFailed is an integer, not a long.
We need APIs in DataStore to handle this different data type, as
otherwise it will result in an unnecessary cast from long <-> int, which
is a lossy conversion.

Simplify the Android CT properties
Since we are moving away from runtime flags, the CT URLs for the log
list, signature, and public key will be hardcoded. I took the occasion
to simplify the logic for handling the Android CT properties and removed
the various "_PENDING" properties. They were making everything much
harder to follow.

Add SignatureVerifier class to handle public keys from different sources
The SignatureVerifier class allows setting a public key either as a
string or as a file. The former method is used when the key is read from
a flag via the CertificateTransparencyFlagsListener. The latter method
is used when the key is downloaded as a file by the daily
CertificateTransparencyJob.

This CL also adds an additional step to download a public key from a
URL via the CertificateTransparencyDownloader. Now the class goes
through the following steps:
1. Download a public key from the public key url,
2. If successful, download a log list signature from the metadata url,
3. If successful, download log list from the content url,
4. If successful, verifiy the log list using signature and public key,
5. If successufl, install the log list.

I also realized the CertificateTransparencyDownloaderTest was really
hard to understand, even for me that I wrote it xD
I attempted to clean up the test, hopefully it is a bit clearer now.
I'll probably make a second simplification pass in a follow-up CL.

Log CT log list download failures
This CL adds a DownloadStatus class inside the DownloadHelper. The class
acts as a thin wrapper around the status and reason Ids returned by the
DownloadManager, with some utility methods to help with the
interpretation of the download status.

Add compatibility version to log lists installed by CT
Introduce a CompatibilityVersion class to group installing operations on
log list related to the same compatibility version (e.g, v3).

Add support for multiple compatibility versions to the

there exists only one compatibility version.

the log list data, contains a signature generated using the public key
