Changing `memory` option to limit resident memory instead of virtual memory, in config file and fdbserver/fdbbackup/fdbcli command-line argument. Since `rlimit` doesn't support limiting virtual memory, the current implementation have both of fdbmonitor and the fdbserver/fdbbackup process checking process RSS periodically and kill and restart the process if the limit is exceeded.
Adding a new `memory_vsize` option to limit virtual memory, if backward-compatible behavior is desired.

* Change DNS cache to use std::map.
Revert commit 90c259d84e, because if we use unordered_map, toString() can be inconsistent.
* Move ClientKnob::COORDINATOR_HOSTNAME_RESOLVE_DELAY to FlowKnob::HOSTNAME_RESOLVE_DELAY.
* Move Hostname to its own files.
Also, add resolve-related variables and functions in Hostname.
In commit 99b030c2f6, it is allowed to set
knob values in TOML file per single test, using syntax
[[test]]
[[test.knobs]]
knob_key = knob_value
the knob key/value pairs are changed before the TEST_CASE starts, then
reverted after TEST_CASE completes.
With this patch, it is possible to *globally* update the knob value,
i.e.
[[knobs]]
enable_encryption = true
[[test]]
testTitle = 'EncryptKeyProxy'
[[test.workload]]
testName = 'EncryptKeyProxyTest'
This is manually tested by printing out knob key/value pairs. Also
tested using Ata's EncryptKeyProxy test code by enabling
enable_encryption key.
