sshpeer: allow for additional environment passing to ssh exe

We already have the ability to customize the ssh command line arguments, let's
add the ability to customize its environment as well.

Example use-case is ssh.exe from Git on Windows. If `HOME` enviroment variable
is present and has some non-empty value, ssh.exe will try to access that
location for some stuff (for example, it seems for resolving `~` in
`.ssh/config`). Git for Windows seems to sometimess set this variable to the
value of `/home/username` which probably works under Git Bash, but does not
work in a native `cmd.exe` or `powershell`. Whatever the root cause, setting
`HOME` to be an empty string heals things. Therefore, some distributors
might want to set `sshenv.HOME=` in the configuration (seems less intrusive
that forcing everyone to tweak their env).

Test Plan:

Create a repo with whitespace only changes

  $ hg init repo-with-whitespace
  $ cd repo-with-whitespace
  $ cat > foo << EOF
  > line 0
  > line 1
  > line 2
  > line 3
  > EOF
  $ hg -q commit -A -m 'commit 0'
  $ cat > foo << EOF
  > line 0
  > line 1 modified by 1
  > line 2
  > line 3
  > EOF
  $ hg commit -m 'commit 1'
  $ cat > foo << EOF
  > line 0
  > line 1 modified by 1
  >     line 2
  > line 3
  > EOF
  $ hg commit -m 'commit 2 (leading whitespace on line 2)'
  $ cat > foo << EOF
  > line 0
  > line 1 modified by 1
  >     line 2
  > EOF
Need to use printf to avoid check-code complaining about trailing whitespace.
  $ printf 'line 3    \n' >> foo
  $ hg commit -m 'commit 3 (trailing whitespace on line 3)'
  $ cat > foo << EOF
  > line  0
  > line 1 modified by 1
  >     line 2
  > EOF
  $ printf 'line 3    \n' >> foo
  $ hg commit -m 'commit 4 (intra whitespace on line 0)'
  $ cat > foo << EOF
  > line  0
  > 
  > line 1 modified by 1
  >     line 2
  > EOF
  $ printf 'line 3    \n' >> foo
  $ hg commit -m 'commit 5 (add blank line between line 0 and 1)'
  $ cat > foo << EOF
  > line  0
  > 
  > 
  > line 1 modified by 1
  >     line 2
  > EOF
  $ printf 'line 3    \n' >> foo
  $ hg commit -m 'commit 6 (add another blank line between line 0 and 1)'

  $ hg log -G -T '{rev}:{node|short} {desc}'
