Enhanced few exsiting PIM APIs to support both
IPv4 and IPv6 configuration. Added few new APIs
for PIMv6. Tested all existing tests with new
API changes.

This PR adds support for configuring topotest routers using a single file.
instead of:
```
router.load_config(
TopoRouter.RD_ZEBRA, os.path.join(CWD, "{}/zebra.conf".format(rname))
)
router.load_config(
TopoRouter.RD_OSPF, os.path.join(CWD, "{}/ospfd.conf".format(rname))
)
router.load_config(
TopoRouter.RD_BGP, os.path.join(CWD, "{}/bgpd.conf".format(rname))
)
```
you can now do:
```
router.load_frr_config(
os.path.join(CWD, "{}/frr.conf".format(rname)),
[TopoRouter.RD_ZEBRA, TopoRouter.RD_OSPF, TopoRouter.RD_BGP]
)
```
or just:
```
router.load_frr_config(os.path.join(CWD, "{}/frr.conf".format(rname)))
```
In this latter case, the daemons list will be inferred from frr.conf file.

Create a pid file for the router created by topotest.
By executing nsenter directly against this pid, developers
can execute commands directly from outside the unet shell.
This allows the developer to use script, tab completion, etc.,
and improves efficiency.

TMUX and Screen support when running topotests inside docker. This
allows the gdb, shell and vtysh features to correctly work even when
running the tests inside docker.
Add options:
--asan-abort :: aborts the process on ASAN errors
--strace-daemons :: strace some or all daemons

This new daemon manages Segment-Routing Traffic-Engineering
(SR-TE) Policies and installs them into zebra. It provides
the usual yang support and vtysh commands to define or change
SR-TE Policies.
In a nutshell SR-TE Policies provide the possibility to steer
traffic through a (possibly dynamic) list of Segment Routing
segments to the endpoint of the policy. This list of segments
is part of a Candidate Path which again belongs to the SR-TE
Policy. SR-TE Policies are uniquely identified by their color
and endpoint. The color can be used to e.g. match BGP
communities on incoming traffic.
There can be multiple Candidate Paths for a single
policy, the active Candidate Path is chosen according to
certain conditions of which the most important is its
preference. Candidate Paths can be explicit (fixed list of
segments) or dynamic (list of segment comes from e.g. PCEP, see
below).
Configuration example:
segment-routing
traffic-eng
segment-list SL
index 10 mpls label 1111
index 20 mpls label 2222
!
policy color 4 endpoint 10.10.10.4
name POL4
binding-sid 104
candidate-path preference 100 name exp explicit segment-list SL
candidate-path preference 200 name dyn dynamic
!
!
!
There is an important connection between dynamic Candidate
Paths and the overall topic of Path Computation. Later on for
pathd a dynamic module will be introduced that is capable
of communicating via the PCEP protocol with a PCE (Path
Computation Element) which again is capable of calculating
paths according to its local TED (Traffic Engineering Database).
This dynamic module will be able to inject the mentioned
dynamic Candidate Paths into pathd based on calculated paths
from a PCE.

Change the public router stop method to always do a two-phase
shutdown - once without waiting and a second time with a wait.
Ordinary callers need to use this approach when stopping routers.
Move the detailed internal details to a private method that tests
should not call directly.

Start the cleanup of diagnose_env to allow the running of topotests
on platforms besides linux.
So we split up diagnose_env into linux and freebsd variants.
At this point in time freebsd doesn't have any special code.
