* template: Fix passing `trim_blocks' inline
Fix passing `trim_blocks' option to the template module as inline
argument. Previously passing the `trim_blocks' option inline instead of
using the YAML dictionary format resulted in it always being set to
`True', even if `trim_blocks=False' was used.

* template: Add option to `lstrip_blocks'
Add option to set `lstrip_blocks' when using the template module to
render Jinja templates. The Jinja documentation suggests that
`trim_blocks' and `lstrip_blocks' is a great combination and the
template module already provides an option for `trim_blocks'.
Note that although `trim_blocks' in Ansible is enabled by default since
version 2.4, in order to avoid breaking things keep `lstrip_blocks'
disabled by default. Maybe in a future version it could be enabled by
default.
This seems to address issue #10725 in a more appropriate way than the
suggested.

* template: Check Jinja2 support for `lstrip_blocks'
Since the `lstrip_blocks' option was added in Jinja2 version 2.7, raise
an exception when `lstrip_blocks' is set but Jinja2 does not support it.
Check support for `lstrip_blocks' option by checking `jinja2.defaults'
for `LSTRIP_BLOCKS' and do not use `jinja2.__version__' because the
latter is set to `unknown' in some cases, perhaps due to bug in
`pkg_resources' in Python 2.6.6.
Also update option description to state that Jinja2 version >=2.7 is
required.
