Previously, the Allocate method of the daemon always created a new Lease
object. However, as both the CNI ADD and CHECK commands call Allocate,
and CHECK can be called multiple times, this resulted in multiple Lease
objects being created per pod.
Each of these leases was long lived with its own maintain() loop -
however the daemon only kept track of the most recent one, meaning any
old lease objects remained running forever (and held open their NetNS
files). After a long enough period, this resulted in the system crashing
out with "too many files" or a similar error limits-related error.
This commit updates the behaviour of Allocate() to first check if a
Lease already exists for the given clientID. If none is found, one is
created as before. If a Lease is found, a new Check() mechanism is
called, which simply wakes up the maintain() loop to cause it to check
the status of the lease.
This may fix #329.

These were previously left intact, even when exiting gracefully. As the
daemon also fails if the socket already exists, it became the caller's
responsibilityto check for and cleanup old socket files when performing
graceful / deliberate restarts.

Currently, hostname is set in the original DHCPREQUEST but not the
renewal. With some DHCP server implementations (such as FreeBSD dhcpd),
this leads to the hostname being cleared in the lease table.
This behavior is inconsistent with other DHCP clients such as dhclient
which set the hostname on the renewal request as well. To fix, use the
same options for acquire and renew.
This is compatible with RFC 2131 (see table 5).

The client id was constructed differently in the acquire
function compared to the release and renew functions,
which caused the dhcp-server to consider it a different client.
This is now encapsulated in a common function.

First byte of client ID is type, instead of value. See this from
RFC2132:
Code Len Type Client-Identifier
+-----+-----+-----+-----+-----+---
| 61 | n | t1 | i1 | i2 | ...
+-----+-----+-----+-----+-----+---

Almost every first retry of DHCP will fail due to interface is not up. Add a
fast retry to reduce unnecessary latency.

With this patch, when the IPs are provisioned via CNI args or via
`RuntimeConfig` the CIDR is only parsed once.

This commit addresses the scenarios when the invalid CIDR is
provisioned via:
- CNI_ARGS
- RuntimeConfig

The default lease acquisition timeout of 62 seconds is way too long when
running multiple testcases, overrunning the `go test` timeout of 10m. Let
testcases specify a shorter timeout.
