Add vpp specific properties to ip addresses for use in the api.
.vapi_af -- returns [ADDRESS_IP4, ADDRESS_IP6]
.vapi_af_name -- returns the string ['ip4', 'ip6']
Update tests to demonstrate usage.

from the API doc, a table replace is:
"
The use-case is that, for some unspecified reason, the control plane
has a very different set of entries it wants in the table than VPP
currently has. The CP would thus like to 'replace' VPP's current table
only by specifying what the new set of entries shall be, i.e. it is not
going to delete anything that already eixts.
the CP delcartes the start of this procedure with this begin_replace
API Call, and when it has populated all the entries it wants, it calls
the below end_replace API. From this point on it is of coursce free
to add and delete entries as usual.
The underlying mechanism by which VPP implements this replace is
purposefully left unspecified.
"
In the FIB, the algorithm is implemented using mark and sweep.
Algorithm goes:
1) replace_begin: this marks all the entries in that table as 'stale'
2) download all the entries that should be in this table
- this clears the stale flag on those entries
3) signal the table converged: ip_table_replace_end
- this removes all entries that are still stale
this procedure can be used when an agent first connects to VPP,
as an alternative to dump and diff state reconciliation.

format_vl_api_prefix_t returns a dict with keys 'address' and 'address_length',
but other format_vl_api_prefix functions return a dict with 'prefix', and 'len'.
Refactor all format_vl_api_prefix_t to return consistent keys 'address' and 'len'.

Enhance the route add/del APIs to take a set of paths rather than just one.
Most unicast routing protocols calcualte all the available paths in one
run of the algorithm so updating all the paths at once is beneficial for the client.
two knobs control the behaviour:
is_multipath - if set the the set of paths passed will be added to those
that already exist, otherwise the set will replace them.
is_add - add or remove the set
is_add=0, is_multipath=1 and an empty set, results in deleting the route.
It is also considerably faster to add multiple paths at once, than one at a time:
vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.11
100000 routes in .572240 secs, 174751.80 routes/sec

If you pass in a non-unicode 4-byte ipv6 address to ip_address,
ipaddress interprets this as an IPv4Address.
Under python2, ip_address interprets 'a7::' as a packed ipv4:
97.55.58.58
You can test with:
---
import ipaddress
try:
text_type = unicode
except NameError:
text_type = str
addr = ipaddress.ip_address('a7::')
print(addr)

The API calls that use any of vl_api_address_t, vl_api_ip4_address,
vl_api_ip6_address_t, vl_api_prefix_t, vl_api_ip4_prefix_t,
vl_api_ip6_prefix_t now accepts either the old style dictionary,
a text string (2001:db8::/32) or an ipaddress ojbect.
Unless it is called with '_no_type_conversion':True, it will
also return an appropriate ipaddress object.
