Account-level metric config

[bretg]

One of the most expensive parts of hosting metrics is the account-level metrics.

It's possible to completely turn off all metrics for all accounts, but sometimes we want to monitor certain accounts for specific changes, or consistently monitor a few bellweather accounts for general health.

Currently the config allows global control with these server options:

• metrics.accounts.default-verbosity
• metrics.accounts.basic-verbosity: a list of accounts for which only basic metrics will be submitted
• metrics.accounts.detailed-verbosity: a list of accounts for which verbose metrics will be submitted

However, updating these values requires a deploy. We'd prefer to be able to build a user interface to set the metrics level for each account to be able to change them through the database.

So we propose adding a flag that would set the "account.ACCOUNTID" metrics.

account properties config (from the file)

metric-level: "none", "basic", "verbose"

account config (from DB query)

metric-level: "none", "basic", "verbose"

Note that this is another example of the increasing number of configurations in the Accounts table as discussed in #1672
